Lithium batteries for electric cars overheat with disastrous consequences
Posted by angelina in Oct 20, 2009, under Uncategorized
Short-circuit or internal damage occurs may lead to a variety of the latest generation of lithium-ion batteries overheating phenomenon, prevalent in electronic products in this issue of electric cars could have disastrous consequences.
It appears that the summer of 2009 is considered as a milestone in the green car.
In July, located in Tokyo, Japan, Mitsubishi Motors announced the news of its 48,000 U.S. dollars of electric micro-car i-MiEV to go on sale this month, an official, and with the market already Fuji Heavy Industries, Nissan, and BYD’s electric car products to compete.
However, even if car manufacturers are competing in the area show their more avant-garde and come up with a leisurely, pleasant attitude of the electric car, but some technical experts still express a variety of concerns.
Prior to that, they pay more attention to battery life, and life mileage, recently, the technical experts also pointed out a variety of short-circuit or internal damage occurs may lead to the latest generation of lithium-ion batteries overheating phenomenon.
In mobile phones, notebook computers and other electronic products used in the battery, each battery 500-10000000 be one cases of a similar situation – this means that the likelihood of fire.
Laptop battery pack is usually composed of six batteries, electric vehicle battery pack in the capacity for more – probably at least 75 or 80 batteries, which is the underlying subtext – that speeding on the highway electric car, each of 60000, perhaps we will have at least one problem.
“Although this is a small probability event, but the event, the consequences would be catastrophic.” Accelerating the amount of well-known American manufacturer of thermal equipment Tiax’s battery expert Brian Barnett (Brian Barnett) warned.
The problem is that the fire caused by the pavilion zv6000 battery,pavilion dv1000 battery how serious it will be compared with conventional fuels at greater risk of a car on fire do?
“A big risk is that if a battery troubles this problem will be ‘transmitted’ to the battery and other batteries,” the United States AAB (Advanced Automotive Batteries), president of Meinahaimu Anderman (Menahem Anderman ) to the expressed concern, because the current battery technology is still in its infancy, it is difficult to quantify the risk is not negligible.
Even though the battery problems will not be like a normal fire vehicle on fire spread so quickly, but it will be a little bit of land erosion, a key component of the body until it wants to see accidents.
The experts noted that such shortcomings do not immediately appear in the pf723a , hp 367759-001. But the thousands of electric cars are likely to encounter in a moving road mishap from the battery, even if the occupants was not injured, vehicle manufacturers will also have received a heavy blow.
In 2006, due to battery problems Sony VAIO notebook recall, for a loss of 258 million. In electric vehicle, the battery costs account for 50% of the total cost, if there are problems, the loss is much more painful than notebook computers.
Of course, car manufacturers are willing to insist that their cars are safe.
Nissan said they coat the battery uses a special material, low thermal conductivity of these materials, you can minimize the risks of batteries overheating. China’s leading battery technology experts insisted that its iron pavilion dv2000 battery , hp hstnn-lb31 BYD is perfectly safe.
Mitsubishi i-MiEV’s battery was not easy bending deformation of rigid framework to protect them, then added a layer of impact outside of the cage from the chip to control the charge and continue to monitor each and condition of the battery.
Mitsubishi Motors president, Nishioka Bridge (Osamu Masuko) believes that these measures have greatly reduced the risks implied by the battery. In his last two years, has been using a red and white i-MiEV, by a full-time driver to drive for him, it seems that there has not been a big problem.
To ensure safety, the Japanese automobile manufacturers to actively carry out the tests on the battery. For example, Nissan and Mitsubishi’s engineers and, in extreme hot and cold environment, keep the hp f4486b ,hp cgr-b1870ae charge and discharge, and simulate a variety of cell damage situation.
However, the technical experts believe that these measures can not guarantee the eradication of lost potential dangers.
“Unless you put the battery installed into the car and someone opened a few years,” the Tokyo market research firm Fuji economic groups of batteries analyst Seiji Ezaki said, “If you do not actual road test, you do not really know how to use the battery as well as the in a real state of the pavilion zd7000 battery , pp2182d battery will appear to use some kind of situation. “
The Problems with Non-Correctable Battery
Posted by angelina in Jul 08, 2009, under Uncategorized
Some rechargeable batteries can be restored through external means, such as applying a full discharge. There are, however, many defects that cannot be corrected. These include high internal resistance, elevated self-discharge, electrical short, dry-out, plate corrosion and general chemical breakdown.
The performance loss of a battery occurs naturally as part of usage and aging; some is hastened by lack of maintenance, harsh field conditions and poor charging practices. This paper examines the cause of non-correctable compaq laptop battery problems and explores ways to minimize these breakdowns.
High Self-discharge
All armada m700 battery are affected by self-discharge. This is not a defect per se, although improper use enhances the condition. Self-discharge is asymptotical; the highest loss occurs right after charge, and then tapers off.
Nickel-based evo n400c battery exhibit a relatively high self-discharge. At ambient temperature, a new nickel-cadmium loses about 10% of its capacity in the first 24 hours after charge. The self-discharge settles to about 10% per month afterwards. Higher temperature increases the self-discharge substantially. As a general guideline, the rate of self-discharge doubles with every 10°C (18°F) increase in temperature. The self-discharge of nickel-metal-hydride is about 30% higher than that of nickel-cadmium.
The self-discharge increases after a nickel-based evo n410c battery has been cycled for a few hundred times. The battery plates begin to swell and press more firmly against the separator. Metallic dendrites, which are the result of crystalline formation (memory), also increase the self-discharge by marring the separator. Discard a nickel-based battery if the self-discharge reaches 30% in 24 hours
The percentage of self-discharge can be measured with a evo n600c battery analyzer but the procedure takes several hours. Elevated internal battery resistance often reflects in higher internal battery resistance, a parameter that can be measured with an impedance meter or the OhmTest program of the Cadex battery analyzers.
Cell matching
Even with modern manufacturing techniques, the cell capacities cannot be accurately predicted, especially with nickel-based cells. As part of manufacturing, each cell is measured and segregated into categories according to their inherent capacity levels. The high capacity ‘A’ cells are commonly sold for special applications at premium prices; the mid-range ‘B’ cells are used for commercial and industrial applications; and the low-end ‘C’ cells are sold at bargain prices. Cycling will not significantly improve the capacity of the low-end cells. When purchasing rechargeable evo n610c battery at a reduced price, the buyer should be prepared to accept lower capacity levels.
The cells in a pack should be matched within +/- 2.5%. Tighter tolerances are required on batteries with high cell count, those delivering high load currents and packs operating at cold temperatures. If only slightly off, the cells in a new pack will adapt to each other after a few charge/discharge cycles. There is a correlation between well-balanced cells and evo n620c battery longevity.
Quality cells are more consistent in capacity and age more evenly than the lower quality counterparts. Manufacturers of high-end power tools choose high quality cells because of durability under heavy load and temperature extremes. The extra cost pays back on longer lasting presario 1800 battery packs.
lithium-based cells are by nature closely matched when they come off the manufacturing line. Tight tolerances are important because all cells in a pack must reach the full-charge and end-of-discharge voltage thresholds at a unified time. A built-in protection circuit safeguards against cells that do not follow a normal voltage pattern.presario 700 battery,presario 900 battery , presario 1700 battery ,armada e500 battery.
Recycling batteries
Posted by angelina in Jul 08, 2009, under Uncategorized
Modern batteries are often promoted on their environmental qualities. lithium-based batteries fall into this category. While nickel-cadmium presents an environmental problem on careless disposal, this chemistry continues to hold an important position among rechargeable batteries. Power tools are almost exclusively powered by nickel-cadmium. Lead-acid batteries continue to service designated market niches and these batteries also need to be disposed of in a proper manner. lithium-ion would simply be too fragile to replace many of these older, but environmentally unfriendly, toshiba pa3591u-1brs chemistries.
Our quest for portability and mobility is steadily growing, so is the demand for batteries. Where will the mountains of toshiba portege 4000 battery go when spent? The answer is recycling.
The lead-acid battery has led the way in recycling. The automotive industry should be given credit in organizing ways to dispose of spent car batteries. In the USA, 98% of all lead-acid tecra 8100 battery are recycled. In comparison, only one in six households in North America recycle batteries.
Careless disposal of nickel-cadmium is hazardous to the environment. If used in landfills, the cadmium will eventually dissolve itself and the toxic substance can seep into the water supply, causing serious health problems. Our oceans are already beginning to show traces of cadmium (along with aspirin,satellite 1900 battery, penicillin and antidepressants) but the source of the contamination is unknown.
Although nickel-metal-hydride is considered environmentally friendly, this chemistry is also being recycled. The main derivative is nickel,satellite a60-662 battery, which is considered semi-toxic. nickel-metal-hydride also contains electrolyte that, in large amounts, is hazardous. If no disposal service is available in an area, individual nickel-metal-hydride batteries can be discarded with other household wastes. If ten or more batteries are accumulated, the user should consider disposing of these packs in a secure waste landfill.
Lithium-ion satellite a65 series used for cell phones and laptops do not contain metallic lithium and the disposal problem does not exist. Most lithium systems contain toxic and flammable electrolyte.
Europe and Asia have had programs to recycle spent fujitsu laptop battery for many years. Sony and Sumitomo Metal in Japan have developed a technology to recycle cobalt and other precious metals from spent lithium?ion batteries.
Battery recycling plants require that the batteries be sorted according to chemistries. Some sorting must be done prior to the battery arriving at the recycling plants. nickel-cadmium, nickel-metal-hydride, lithium?ion and lead acid are placed in designated boxes at the collection point. Battery recyclers claim that if a steady stream of fujitsu fpcbp80, sorted by chemistry, were available at no charge, recycling would be profitable. But preparation and transportation add to the cost.
The recycling process starts by removing the combustible material, such as plastics and insulation, with a gas fired thermal oxidizer. Gases from the thermal oxidizer are sent to the plant’s scrubber where they are neutralized to remove pollutants. The process leaves the clean,fujitsu fpcbp77, naked cells, which contain valuable metal content.
Cadmium is relatively light and vaporizes at high temperatures. In a process that appears like a pan boiling over, a fan blows the cadmium vapor into a large tube,fujitsu fpcbp68, which is cooled with water mist. This causes the va
Not all countries base the cost of recycling on the battery chemistry; some put it on tonnage alone. The flat cost to recycle fujitsu fpcbp63 is about $1,000 to $2,000US per ton. Europe hopes to achieve a cost per ton of $300US. Ideally, this would include transportation, however, moving the goods is expected to double the overall cost. For this reason, Europe sets up several smaller processing locations in strategic geographic locations.
Important: Under no circumstances should batteries be incinerated as this can cause explosion. If skin is exposed to electrolyte, flush with water immediately. If eye exposure occurs, fujitsu fpcbp95, flush with water for 15 minutes and consult a physician immediately
Charging battery at high and low temperatures
Posted by angelina in Jul 08, 2009, under Uncategorized
Rechargeable batteries operate under a reasonably wide temperature range. This, however, does not automatically permit charging under these same temperature extremes. While operating batteries under hot or cold conditions cannot always be avoided, the user has some control over charging. Efforts must be made to charge the batteries at moderate temperatures.
Nickel-cadmium: In general, older Toshiba laptop battery technologies are more tolerant to charging at temperature extremes. Nickel-cadmium can be fast-charged in an hour or so, however, such a charge should only be applied within temperatures of 5°C and 45°C (41°F and 113°F). More moderate temperatures of 10°C to 25°C (50°F to 77°F) produce better results.
Charging below 5°C requires a reduce charge rate of 0.1C (one tenth of the rated current). This is in line with the rate at which the oxygen and hydrogen can be absorbed within the cell. Because of the decreased combination rate at low temperatures, too rapid a charge would cause excessive cell pressure, which would lead to cell venting. Such a toshiba pa2487u battery would never reach full charge state under these conditions.
Industrial batteries that need to be fast-charged at low temperatures include a thermal blanket to maintain the toshiba pa3107u-1brs at an acceptable temperature. Once a charging temperature is enabled, the very process of gas recombination, which occurs during charge, also generates some heat to assist the cold temperature charging. The ideal charger would adjust itself to obtain equilibrium between gas recombination and charge current.
Nickel-metal-hydride is less forgiving than the nickel-cadmium if charged under high and low temperatures. Nickel-metal-hydride cannot be fast charged below 10°C (45°F),toshiba pa3383u-1brs, neither can it be slow charged below 0°C (32°F). Some industrial chargers are designed to adjust the charge rate to existing temperatures. Price sensitivity does not permit elaborate temperature sensing on consumer chargers.
At higher temperatures, the charge acceptance of nickel-based toshiba pa3384u-1brs is drastically reduced. A battery that provides a capacity of 100% when charged at moderate room temperature can only accept 70% if charged at 45°C (113°F), and 45% if charged at 60°C (140°F). This demonstrates the poor summer performance of some vehicular chargers.
Lithium- ion offers good charging performance at cold and hot temperatures. The acceptable charge range is 0° to 45°C (32°F to 113°F). It is recommended,toshiba pa3285u-1brs, however, to reduce the charge rate to less than 1C at temperatures of 5°C to 0°C (41°F to 32°F).
It is important to know that consumer grade lithium-ion toshiba pa3191u-1brs cannot be charged below 0°C (32°F). Although the packs appear to be charging normally at freezing temperatures, the cell impedance goes up and the acceptance of the ions on the anode is drastically reduced.
What is most troubling is the plating of metallic lithium that occurs on the anode. The higher the charge rate, the more pronounced the plating will be. A prolonged charge at cold temperatures will eventually compromise the safety of the pack. The plating is permanent and no amount of cycling can reverse this effect. Unknown to the user, such a toshiba pa3166u-1brs will become more vulnerable to failure if subjected to impact, crush or high rate charging. Venting with flame could be the result.
There are specialty Li-ion batteries that allow low-temperature charging. These packs are made for military and aerospace applications. The lower viscosity of the electrolyte of these toshiba pa3331u-1brs may reduce the rate capability and decrease the cycle life. Beside lower performance, the high purchase price is another concern for the consumer.
There are also safety concerns when using lithium-ion at high temperatures, especially in cells containing cobalt and/or nickel electrodes. Raising the temperature of a fully charged cell, or applying an overcharge,toshiba pa3084u-1brs could cause a spontaneous thermal runaway. The higher the state-of-charge, the less heat is required to induce a thermal runaway. Manganese based cells [spinel] are thermally more stable and the thermal stability is the same whether fully charged or overcharged.
Lead-acid is reasonably forgiving on temperature extremes, as we are familiar with our car batteries. Part of this tolerance is credited to the sluggishness of the lead-acid system. Some toshiba pa3399u-1brs brands permit freezing and low level charging; others sustain damage and deliver reduced capacity and a short service life.
Heat kills batteries. The warmer the cells, the shorter the life is. Elevated temperatures cannot always be prevented,toshiba pa3395u-1brs, especially during fast charging, but efforts must be made to keep this time brief. While 45°C (113°F) is acceptable if kept short, at 50°C (122°F) and above, the battery starts to suffer. Note that the cells inside the pack are always a few degrees warmer than the temperature of the housing.
Ultra-fast chargers
Some charger manufacturers claim amazingly short charge times of 30 minutes or less. With well-balanced cells and operating at moderate room temperatures, nickel-cadmium toshiba pa3250u-1brs designed for fast charging can indeed be charged in a very short time. This is done by simply dumping in a high charge current during the first 70% of the charge cycle.
Ultra-fast charging can only be applied to toshiba pa3356u-1brs that are designed for fast charging. Applying a high current charge to regular cells will cause the conductive path to heat up. The contacts on portable packs also suffer if the current handling of the spring-loaded plunger contacts is underrated. These contacts may wear out prematurely. Often, a fine and almost invisible crater appears on the tip of the contact, which causes a high resistive path or forms an isolator. The heat generated by a bad contact often melts the plastic. Higher contact tensions improve the current flow.
Some advanced chargers regulate the charge current according to the battery’s ability to accept charge. An empty toshiba pa3291u-1brs ,toshiba pa3506u-1brs will initially take a very high charge current. Towards the end of a charge, the current is tapered down. Aged batteries are given their due respect and are automatically charged at rates suitable to their condition.
Alcohol fuel-cell concept of cell phone exposure Cheers

Conductive brush is available ,which promote bio-fuels battery to have a major breakthrough
Posted by angelina in Jul 06, 2009, under Uncategorized
University of Georgia researchers have successfully developed a few days ago of molecular conductive brush. The invention is significant because it means that mankind has to manufacture for the pacemaker,notebook battery,cochlear implant, prostheses and other precision instruments, bio-power fuel cells has taken the first step. United Kingdom, “Chemical Science” magazine, said the technology as “the field of nano-technology a major breakthrough.”
Project by the University of Georgia chemist and two other co-completion of graduate school. They invented by the polymer brush chain and benzene thiophene chain attached to the ultra-thin film on top of books consisting of metal, of which benzene is the simplest aromatic molecule,acer batcl50l , can be used to produce chemical solvents, which contain a thiophene sulfur heteroatom five million heterocyclic compounds, present in coal tar and shale oil.
Lochlyn said brush is the molecule attached to the metal surface, high density polymer chain. Its structure similar to toothbrushes, metal film is brush handle,travelmate 290 battery, and the polymer is the equivalent of a brush. The researchers of this type of surface will be referred to as “polymer brush.” In order to create a structure closely linked with the polymer chain, researchers must use “grafting” approach to growth in the metal surface.
By using this method,travelmate 4000 battery, the scientists first put a layer of thiophene thin film as a “surface”; and then the scientists used the method of polymerization in the basis of previous and gradually establish a chain of thiophene or benzene chain.
Lochlyn also said that the charm of the organic semiconductor is that its properties can be contained in the light of their own to change the number of organisms. For example, thiophene is an insulator, but when people use a certain technology will be a large number of elements linked to thiophene, the thiophene have a conductive polymer in nature. The thin film of polymer brush only 5-50 nanometers thick,travelmate 2300 battery, so even if the thickness is high optical microscope can not see.
The invention of micro-bio-fuel cells for the development of the good news. Lochlyn said that if the invention can take advantage of the energy source of the human body (such as glucose) of the bio-fuel cells, implanted in the body of the instrument will no longer need to replace the battery, but want to do this is not easy. For example, the body of the enzyme can be a very good chemical energy into electrical energy, but want to make use of enzymes for battery-powered but it is very difficult,aspire 1680 battery , because the human body contains natural enzymes to protect the insulating layer, which can prevent the electronic from the activity transferred to the electrode site. Lochlyn who want them to brush invention can provide a better load flow channel.
Lochlyn but at the same time that the research is still only in its infancy. Before them there are many obstacles,aspire 1410 battery, such as their charge is not aware of the many organic materials through the basic physical principles.
Lochlyn and his research team next plan is to take advantage of the invention “molecular brush” the appropriate equipment, such as chemical and biological sensors, artificial limbs, pacemakers, cochlear implant,travelmate 4500 battery,acer lcbtp03003 ,acer aspire 1300 , acer btp-apj1 , acer btp-aqj1 , acer btp-arj1 ,asus a42-a3 such as. If the experiments succeed, “molecular brush” to avoid these instruments and the human body have a living tissue rejection.

Attention to the quality of batteries
Posted by angelina in Jul 02, 2009, under Uncategorized
Taiwan manufacturers have emerged in the quality of the battery, Solarbe informed the purchase of component manufacturers be careful
Solar cells of crystalline silicon solar cells is the core component packaging materials. In recent years due to the international solar energy photovoltaic industry has developed rapidly, the market was in short supply for PV products. However, after the financial crisis, market shrinkage, customer requirements for components, “high quality”, which came a few days ago after another component of domestic incident has been returned by the survey, some battery makers in Taiwan low-quality battery is the problem lies.
Which the individual solar cell manufacturers in pursuit of profits, ignore the quality of products, regardless of the market risk component manufacturers will be directly sold to the issue of cell-chip components manufacturers, component manufacturers in the problem and are subject to significant economic loss, but also components manufacturers ignored the complaints, sony laptop battery,has deliberately avoided. To the makers of the film from the battery to bear the enormous risks and losses are fully passed on to the packaging plant components.
Shandong high-tech photovoltaic power Connaught Limited (hereinafter referred to as photovoltaic power Connaught) is Taiwan’s E-ton Solar Tech Co., Ltd (hereinafter referred to as pass energy benefits) of crystalline silicon solar cells using the customers benefit in the use of pass-ray polycrystalline to 156 cells into a component package sent to European clients, without the use of storage at room temperature only after a certain period of time large-scale phenomenon in the back of drum package(sony pcga-bp1n ).

Ni-MH battery car policy ushered in by the acceleration phase
Posted by angelina in Jul 02, 2009, under Uncategorized
Casting consultant in industrial research center was informed that the letter of the Ministry of Public Works yesterday announced a “new energy automobile production enterprises and the rules governing market access for their products”, and July 1 will come into effect until December 31, 2010 apply.

Product development period to allow for mass production, only in approved areas, the scope, duration and conditions of the sale, use, and at least 20% of the sales of products for real-time monitoring of running status. Stage products and products of conventional car “vehicle manufacturers and product announcement” management the same way as in the sale, use the same conventional automotive products.
For consultants in the new energy automotive industry researcher Sheng-mao said that in the development of new energy vehicles,hp f4809a, nickel metal hydride battery technology the most mature, the next 5 years will remain the mainstream of new energy vehicles, and in the next 10 years or so, Ni-MH battery technology and lithium iron phosphate, hydrogen fuel cell two-thirds of the world.
Nickel-metal hydride hp 367759-001 in the field of technology and resources we have the advantage of nickel hydroxide in our country a world leader in performance, rare earth rich in resources, with natural resources, therefore, the development of nickel-hydrogen battery is currently the most realistic option. Lithium-ion power batteries in the tracking of materials to international standards of our research and development stage, many of the raw materials are at the core of research, such as cathode materials and electrolyte, only China can really master the production of these raw materials and manufacturing processes, can be a large-scale promotion.
At present, the nickel-metal hydride hp VGP-BPS5 in the domestic field, Section power far [16.99 2.66%] (600478) Chunlan Group and become a major competitor. In addition to the above two, the Steel Rare Earth [18.91 0.37%] (600111), in high-Ju [11.51 5.50%] (600872) and Tianjin Hi-Tech is also in the production of blue nickel-hydrogen batteries, and [-0.66% 17.98 ] (600549), Gene Nickel [21.57 0.51%] (600432) is a nickel-metal hydride battery materials suppliers.
Published in the vote, according to the consultant’s “2009-2012, China’s hp f4812a industry investment analysis and forecast report” shows that energy-saving and environmental protection is the world’s two major themes of development, countries around the world are scrambling to develop energy-saving products such as electric cars. However, the short-term market power battery car will not show all of the cases with lithium batteries, lithium battery technology is mature, the encroachment of Ni-MH battery market will be very slow process. Nickel-metal hydride batteries in the field of technology and resources we have the advantage of nickel hydroxide in our country a world leader in performance, rare earth rich in resources, with natural resources, therefore, the development of nickel-hydrogen battery is currently the most realistic option.
Fujitsu was also the economic analysis of the mainstream nickel metal hydride compaq 319411-001 will be able to continue until the status in 2011, but after 2011 will gradually be eroded lithium batteries nickel metal hydride battery market share, the agency estimated in 2009 Ni-MH rechargeable car battery with a global market size will grow 23.7 percent over the previous year, reaching ￥ 92,000,000,000, but the car in 2015 with Ni-MH rechargeable battery market size will be reduced to ￥ 55,000,000,000.
