July 1, begin to carry out-new energy automobile manufacturing companies and product access management rules,” which states that “the use of lead-acid battery hybrid passenger cars, pure electric and pure electric passenger cars, commercial vehicles, and the use of metal hydride Nickel-powered hybrid vehicle is classified as mature products. “Prior to the loudest voices were included in the lithium cell vehicle development stage, not a large-scale promotion of the column.

Conducted in Frankfurt, Germany Frankfurt auto show in order to Daimler – Benz, Volkswagen, Toyota car dealer, represented expressed their optimistic about the development of lithium batteries, and a series of Li-ion laptop battery pack equipped with the hybrid to reduce vehicle carbon emissions. Such as the Toyota van in carbon emissions of a mere 60 g / km (average annual emissions from ordinary cars 5000 kilograms).

Then prospects for lithium batteries in the end?

New energy electric car the most important components is the driving force batteries(gd761,kd476), electric motors and energy conversion control system. The new energy vehicles demanding on the battery, you must have a high specific energy, high specific power, fast charging and deep discharge performance, and requires the lowest possible cost, service life as long as possible. Therefore, the power battery is a technical threshold of the highest, is also the most concentrated part of the profits.

Lithium batteries into the fast-growth period

More auto manufacturers choose lithium batteries as a new energy vehicles motive power, industrial output value contains huge potential.

The traditional lead-acid batteries, nickel-cadmium batteries and nickel-metal hydride battery technology itself is relatively mature, but they are used in automotive batteries as a power, there are still major problems. Li-ion battery(VGP-BPS2C,VGP-BPS2A) has a small size, light weight, high voltage (which is nickel-cadmium batteries, nickel-hydrogen batteries 3 times) than the energy of large (up to 165WH / kg, nickel-hydrogen batteries 3 times), cyclic long-lived, self – discharge rate is low, no memory effect, no pollution, safety, and good, therefore, car manufacturers more choices of energy use lithium batteries as a new car battery power.

China’s lithium-ion battery industry began late in Japan, but developing very fast in recent years, especially in the power lithium-ion battery(inspiron e1705 battery,xps m1330 battery) research and development invested a great deal of financial and material resources. China’s automotive lithium-ion battery R & D project has been the national “863″ key project, much of the material to achieve the localization and the introduction of multi-national has been self-built production lines and supporting materials, factories have more than one, have been the formation of large-scale production, intense market competition.

Lithium battery industry as car tremendous value inherent potential of electric vehicles battery materials upstream suppliers and downstream of the car manufacturers have begun to enter the automotive battery business. Li-ion battery is behind the hot car prices on the plug-in hybrids (also known as plug-in hybrid electric vehicles) and pure electric vehicle market prospects of the recognition and R & D capabilities of their current concerns.

Such as the United States Ford, Toyota, Mitsubishi, Nissan, Hyundai, France, Courreges, Ventury and other companies have started their own lithium battery Motor Vehicle Program. While the domestic car manufacturer BYD, Geely, Chery, Lifan, ZTE and other car firms also have their own hybrid and pure electric vehicle powered by lithium battery power.

Therefore, from the development cycle, the current automotive lithium battery market is out of the start-up stage and started into rapid growth stage.

Insufficient to resolve the charge and over-discharge phenomena

safety performance and vehicle power battery management system is the bottleneck of the development of lithium batteries.

At present, the downstream enterprises in China BYD, Wanxiang Group, Shenzhen BAK Battery, Tianjin Lishen Battery and the United States Myers joint ventures. At present the only control vehicle lithium ion phosphate battery pack(inspiron b120 battery,inspiron b130 battery) large-scale production technology, BYD Company, has officially launched its self-developed battery-powered pure electric vehicles E6 and hybrid F3DM.
, However, hinder the development of lithium-ion battery power bottlenecks are: safety performance and vehicle power battery management system.

Automobile manufacturers based on the safety of people-oriented concept, the safety of the battery presented a very high demand. As the vehicle power battery voltage is 12V or 24V, single power lithium-ion battery voltage is 3.7V, so must be used by multiple cells in series, but difficult to achieve because of the battery charge and discharge completely homogeneous, resulting in the battery charge will appear Discharge imbalance, which occurs under charging and over-discharge phenomenon, the situation will lead to a sharp deterioration in battery performance, eventually leading to the entire group of cells does not work, or even scrapped, greatly affect battery life and reliability.

Therefore, power lithium-ion battery to get a good application, need materials, batteries, management systems, taking into account the mechanical processing and other aspects. Therefore, the upstream and downstream enterprises should work together to the battery as the core of the material, the management system requests formation of an industry group, would be conducive to technological advances and system costs.

Midstream materials manufacturers continue to realize the localization and improvement of technical

Cathode materials for lithium battery(gd761,kd476) is high barriers to entry, capacity minimum; anode materials for the industrialization of China has been achieved; electrolysis fluid and membrane technology is still dependent on imports.

Lithium battery materials can be divided into electrode (positive / negative) materials, separator and electrolyte. Li-ion battery cathode material is the core of the current lithium cobalt oxide, lithium manganese, lithium and nickel-cobalt-manganese-based lithium ion phosphate. Ze Yi graphite anode material, solid carbon particle-based; in the middle of positive and negative electrodes while the battery electrolyte and separator.

As high barriers to entry, lithium battery cathode material is the smallest capacity, which is the whole industry chain, the most promising aspect. Cathode materials currently in production companies are: China Baoan, CITIC Anhe Shanshangufen, BYD.

Compared with the cathode materials, anode materials, graphite, solid carbon particle, accounting for the proportion of low-cost lithium batteries(inspiron e1505 battery,inspiron 6000 battery), and the domestic has been achieved industrialization. Currently engaged in lithium battery cathode material production enterprises are the top three Chinese national security, Shanshangufen long shahai capacity. It is worth noting that the current negative electrode materials, while able to basically meet the domestic market demand, but with the increasing popularity of new energy vehicles in future this demand will be a massive shortfall.

Domestic battery manufacturers supporting electrolyte has been basically achieved domestically. The electrolyte lithium hexafluorophosphate main raw materials, accounting for about 50% of the cost of the electrolyte, its production cost is 10 yuan / ton, priced at 40 yuan / ton, gross margin as high as 75%, but the market was largely Kanto Electric the chemical industry, SUTERAKEMI-FA, Morita chemistry, several Japanese companies a monopoly.

Diaphragm materials, the Department of Li-ion technology, the highest barriers to a high value-added material, gross profit margin is usually 70% or more, accounting for the cost of lithium batteries 20 ~ 30%. It is reported that a car need to 1000-2000 m2 membrane. At present, a serious shortage of market supply diaphragm, most dependent on imports, the market dominated by Japanese Asahi Chemical Industry, Tonen Chemical, and the United States Celgard dominate. Domestic companies able to produce membrane only star-source technology, Jinhui High-Tech two technologies are relatively mature.

Upstream resources and technical barriers to seek a breakthrough in

lithium ion phosphate power battery(thinkpad t60 battery) cathode materials, the most promising investment opportunities, but the reserves are limited; simultaneous separation of lithium carbonate in Technology is only a small number of the hands of foreign companies.

Lithium ion phosphate power battery cathode materials, the most promising investment opportunities, the key raw materials, lithium iron phosphate is lithium carbonate, lithium carbonate derived from the mineral resources, in the nature reserves are limited, has a strong regional and scarcity, are scarce resources. Thus, in the new energy automotive industry chain, the strategic importance of lithium carbonate resources become particularly prominent.

At present, the global lithium carbonate industry, the status quo, resource threshold high, capacity is highly concentrated. As of the end of 2007, a major international manufacturers have Chile’s SQM, the United States, FMC and Germany Chemta l l total annual capacity of 78,000 tons, accounting for 80% of global market share. Due to large-scale production enterprise must have reserves of lithium resources are more abundant in salt lake resources, mining rights, making the resources of the industry with higher barriers to entry; the other hand, the vast majority of the world’s resources are high-magnesium salt low lithium type, from the and high-magnesium low lithium brine purification separation of lithium carbonate in the process technology is very difficult, but these techniques only a small number of foreign companies rests in the hands, so the industry is highly technical barriers.

The current domestic production of lithium carbonate enterprises mainly in Tibet, mining, CITIC Guoan, Western Mining Group, Qinghai Salt Lake Group, the four companies, while the Tibetan mining and CITIC Guoan has accounted for the vast majority of , the two companies in 2008 total production of lithium carbonate is not more than 4000 tons.

It is estimated that each new type of electric vehicle needs about 0.08 tons of lithium carbonate, lithium batteries(xps m1330 battery,latitude d830 battery) once the driving force large-scale application of new energy vehicles, only new energy vehicles by 2012 the demand for lithium carbonate will reach 5 million tons. While the domestic prices of industrial-grade lithium carbonate at 4.5 yuan / ton, battery grade lithium carbonate prices by 7 yuan / ton, high purity lithium carbonate price is as high as 10 yuan / ton, the domestic involved in new projects because it is used salt lake brine lithium carbonate extraction, the production cost 10000 ~ 1.5 yuan / tons. Therefore, the market generally felt that the profitability of lithium carbonate products is very high

New virus-built battery could power cars

New virus-built battery could power cars, electronic devices

For the first time, MIT researchers have shown they can genetically engineer viruses to build both the positively and negatively charged ends of a lithium-ion battery.

The new virus-produced batteries have the same energy capacity and power performance as state-of-the-art rechargeable laptop batteries being considered to power plug-in hybrid cars, and they could also be used to power a range of personal electronic devices, said Angela Belcher, the MIT materials scientist who led the research team.

The new batteries, described in the April 2 online edition of Science, could be manufactured with a cheap and environmentally benign process: The synthesis takes place at and below room temperature and requires no harmful organic solvents, and the materials that go into the battery are non-toxic.

In a traditional lithium-ion battery,such as sony vgp-bps2c ,vgp-bps2a , vgp-bps5a battery, lithium ions flow between a negatively charged anode, usually graphite, and the positively charged cathode, usually cobalt oxide or lithium iron phosphate. Three years ago, an MIT team led by Belcher reported that it had engineered viruses that could build an anode by coating themselves with cobalt oxide and gold and self-assembling to form a nanowire.

In the latest work, the team focused on building a highly powerful cathode to pair up with the anode, said Belcher, the Germeshausen Professor of Materials Science and Engineering and Biological Engineering. Cathodes are more difficult to build than anodes because they must be highly conducting to be a fast electrode, however, most candidate materials for cathodes are highly insulating (non-conductive).

To achieve that, the researchers, including MIT Professor Gerbrand Ceder of materials science and Associate Professor Michael Strano of chemical engineering, genetically engineered viruses that first coat themselves with iron phosphate, then grab hold of carbon nanotubes to create a network of highly conductive material.

Because the viruses recognize and bind specifically to certain materials (carbon nanotubes in this case), each iron phosphate nanowire can be electrically “wired” to conducting carbon nanotube networks. Electrons can travel along the carbon nanotube networks, percolating throughout the electrodes to the iron phosphate and transferring energy in a very short time.

The viruses are a common bacteriophage, which infect bacteria but are harmless to humans.

The team found that incorporating carbon nanotubes increases the cathode’s conductivity without adding too much weight to the battery. In lab tests, batteries with the new cathode material could be charged and discharged at least 100 times without losing any capacitance,that is more than traditional lithium-ion battery(gd761,kd476) That is fewer charge cycles than currently available lithium-ion batteries, but “we expect them to be able to go much longer,” Belcher said.

The prototype is packaged as a typical coin cell battery, but the technology allows for the assembly of very lightweight, flexible and conformable batteries that can take the shape of their container.

Last week, MIT President Susan Hockfield took the prototype battery to a press briefing at the White House where she and U.S. President Barack Obama spoke about the need for federal funding to advance new clean-energy technologies.

Now that the researchers have demonstrated they can wire virus batteries at the nanoscale, they intend to pursue even better batteries using materials with higher voltage and capacitance, give vgp-bps2c ,vgp-bps2a a perfect life.such as manganese phosphate and nickel phosphate, said Belcher. Once that next generation is ready, the technology could go into commercial production, she said.

Lead authors of the Science paper are Yun Jung Lee and Hyunjung Yi, graduate students in materials science and engineering. Other authors are Woo-Jae Kim, postdoctoral fellow in chemical engineering; Kisuk Kang, recent MIT PhD recipient in materials science and engineering; and Dong Soo Yun, research engineer in materials science and engineering.

The research was funded by the Army Research Office Institute of the Institute of Collaborative Technologies, and the National Science Foundation through the Materials Research Science and Engineering Centers program.

New laptop battery review

Aug 25

Posted by admin in Uncategorized | Comments off

Battery is generally cylindrical in shape with two terminals, one positive electrode and one negative electrode that conduct electricity along with a substance called electrolyte, that works on the electrodes, chemically and help convert into electrical energy. lenovo Laptop Battery,There is a copper wire that connects the two electrodes. Materials that are used in batteries are carbon, alkaline, chlorine, lithium ion, lead, nickel, sodium, silicon, copper, etc.

Batteries are classified into two- Dry cells and wet cells. The wet cell batteries are also termed storage thinkpad t60 battery , sony vgp-bps2c ,vgp-bps2a battery as they can be recharged as many times as possible. Batteries are also divided as rechargeable and non-rechargeable or disposable batteries. The second type is again termed as primary cells, used till the chemical that produce the electrical current supply is fully consumed, at whicah point the battery is not needed anymore. These types of batteries are used very commonly in ThinkPad Z61t,small and portable piece of equipments that drain low current.

The other type is rechargeable or in other words secondary cells that can be “refueled” even after being completely consumed. For recharging, these batteries need some external help from devices as chargers or re-chargers.

In the present world due to the development of science and technology almost everything (papers, plastics, b,thinkpad t60 battery,thinkpad x60s battery, aluminum, etc.) can be recycled without wasting it by just throwing it after use. Thus we see that recycling is a procedure by which waste products are recovered for reusing, which is also known as waste management.

Laptop Battery recycling falls under electronic waste or e-waste. Here any discarded, broken or unwanted electrical or electronic equipments, ThinkPad Z60t,containing toxic materials are recycled for further use. Batteries like, nickel-cadmium, lead, lithium batteries are made to reuse as the chemicals present in them can cause harm to the environment if allowed to stay long in open air after being discarded by the users. Moreover batteries are regarded as the most expensive energy source and their production requires much valuable recourse, so they are recycled so as to restore those valuable materials gd761,kd476 from those old and used batteries through battery recyling.

Cadmium is a heavy metal and can cause pollution if burned or cremated. To avoid lead pollution lead-aced batteries are processed. This program is considered to be highly successful. Lithium-ion can be very dangerous if exposed to high temperature or sunlight, it can ignite or explode.Therefore battery recycling is a must if we want to protect our environment.

The Recycling Process:

First of all, the batteries to be recycled are sorted according to chemistries such as nickel-cadmium,nickel-metal-hydride, lithium, alkaline etc. The combustible material, such as plastics and insulation, is then removed with a gas fired thermal oxidizer, which is the first step in the recycling process. Most recycling plants have scrubbers where the gases from the thermal oxidizer are neutralized to remove pollutants, producing clean, naked , dell inspiron e1505 battery , sony vgp-bps2c ,vgp-bps2a ,cells that contain precious metal content.

The metal in the inspiron e1505 batteries are then heated to liquefy, after they have been hacked into little pieces. Black slag left by burned out non-metallic substances are scraped off with a slag arm, and the different alloys that settle according to weight are skimmed off. Some plants pour the liquid metals directly into (65 pounds) or ‘hogs’ (2000 pounds) without separating on site, ThinkPad X60 battery,which are then shipped to metal recovery plants to produce nickel, chromium and iron re-melt alloy for the manufacturing of other metal products.

State and Federal Regulations in the United States:

The Mercury-Containing and Rechargeable Battery Management Act was passed in 1996 by the U.S. Congress which requires regulated batteries such as Ni-CD batteries and sealed lead-acid batteries to:

  • 1. be easily removable from consumer products to make it easier to recover them for recycling
  • 2. include in the label the battery chemistry, the “three chasing arrows” symbol,dell KD476 and a phrase that instructs users to properly recycle or dispose the battery
  • 3. provide national uniformity in collection, storage, and transport
  • 4. phase out the use of certain mercury-containing batteries

    • By recycling batteries the environment is not being polluted nearly as much, many natural resources are saved due to the rechargeable laitude d830 battery also. There is a large variety of websites on the Internet with more quality information on recycling batteries.
