Company No. 1 is based in Menlo Park, Calif., plans to sell a new lithium-ion Aspire 3000 battery LCBTP03003 battery anode. This is called Amperex (Amprius) the company argued that the use of this anode, no need to recharge electric vehicles are also allowed to go further, so that mobile devices longer. The lithium-ion anodes prepared now by the son of nano-silicon, the silicon nanowires compared to conventional lithium-ion battery anode manufacture graphite materials with high electrical load capacity of 10 times. According to the company called Amperex, using their new anode batteries, electric cars from an electric charge to go 200 miles to 380 miles, the laptops may work four hours on one charge, extended to 7 hours.

 

While other companies high-end cell designed to provide fast charge and full acceleration of the battery power, Amperex companies try to improve the energy density of battery power to extend that deadline. More batteries energy storage, which supply power to the car or the phone longer. As carmakers turned to electric cars, but like the iPhone, mobile devices such as energy run more intensive applications, if the energy density of the battery and energy consumption resulting a single load can provide the time, they become a more pressing issue. hp Pavilion dv8000 battery  hp Pavilion dv4 battery

 

Lithium-ion battery Lithium-ion on the anode from the cathode to move, while the flow of electrons through an external circuit, reversing the discharge process. As anode material, compared to the currently used graphite, silicon May accept more lithium, which increases the potential. Indeed, the theoretical maximum density of energy of silicon is ten times that of graphite. Burst however, silicon is brittle and easy expansion, although it took a charge cycle.

 

However, the silicon nanowires can be prepared in the cycle of the battery anode repeated continuously without damage. Fall 2009, the founders Amperex, Stanford University Assistant Professor of Materials Science and Engineering, CUI Yi (Yi Cui), showed the structure of nanoparticles of silicon-silicon anodic capacity of storage of the way to achieve the value theoretical and has not broken. Long, thin, soft and easy to bend nanowires pad, which makes when the battery charge and discharge to be soft. The nanowire assembly to form a large surface, which means that the site of interaction with lithium and more. G5266 HD438

 

Amperex enterprise business development manager at Ryan • If Kedeng Tet (Ryan Kottenstette), said the company has significantly improved the growth of nanowires processes to correspond with the high volume production. Line Nm from a catalyst-coated metal substrate gasification. Anode production company did not disclose details, but said that the production process using a matrix more conductive metal catalysts and less expensive. Yi Cui said: “The anode material may be in sheet metal at low cost on a large scale to produce high speed.

 

Currently, the Amperex works with vehicles, communications and electronics manufacturers to phase to prepare, in March raised its first round of venture capital funds venture. The company hopes that next summer to raise funds more difficult to establish a pilot production line.

 

No matter how excellent the anode, the capacity of the battery all also needs to rely on cathode. The performance of lithium ion cathode today is not as developed by the anode rod Amperex’s so. Design first cell of society, through the anode thin and thick corresponding to the cathode means to compensate this lack of proportion. With the same size compared to conventional lithium-ion batteries, design Amperex Company may be stored above 40% capacity load. However, to further improve the energy density, Amperex companies will need to search for new cathode material. XPS M1210 battery XPS M1330 battery

First, the following situation can be recharged Latitude D505 battery Latitude D510 battery

 

1, the battery after one year (if you check the charger, the voltage too high, may need half a year);

 

2, after the new set of insurance;

 

3, to charge a long time do not turn lights, the voltage is maintained at a high level does not turn green time length, and accompanied by drums fever, and even bulb!

 

4, you feel like recovery.

 

Second, the tools of recovery

 

1 bottle of distilled water, go to Wal-Mart to buy Guangdong produces Watson distilled water, 2 large bottles 7 can also buy a bottle of purified water wow. Latitude D520 battery Latitude D600 battery

 

2, a syringe, the formal medical device businesses to buy, buy the biggest, 30ml, and seem to be

 

3, trumpet the word screwdriver, a kind of small, you can also use the type of watch screwdriver (if appropriate, prepare a Phillips screw to open the link).

 

4, clean water, batteries and wash hands a number of wipes 1.

 

5, pvc glue a small bottle, hardware stores are sold, 1 yuan.

 

Third, Method of recovery Latitude D610 battery PC764

 

1, first discharge the battery after the victory, the next weld (twist to open) connection lines, and wipe with a clean cloth, which is followed by the opening of the cover, and each battery has a mouth of ventilation, battery venting means are in shelters on edge to see a gap where it is used in the exhaust, the differences of alignment word screwdriver, screwdriver pat, so that screw into the hole, then down upturned point, and then proceeded to drive a Beat (small battery cover the middle of filming because he was in the ventilation openings on both sides, but the battery of the electric motor needs to turn two measures, because it was the opening in the middle, so as not to damage the rubber inside the cap), Alice and many other occasions, the battery cover down can be Alice, do not be too brutal Although ABS material, but still a distortion too much force.

 

2, after opening the cover, you will find 6 caps (some unscrew the battery), but maybe this time “Leap”, Sheng Liang, flying a rubber cap few, if during the opening the cover does not look like the cover off, slowly eliminated, and hands covered to prevent the rubber cap flying off, because maybe this time the battery internal pressure. Carefully remove rubber cap, white cotton wool is not removed, it is possible. Y9943 Latitude D620 battery

 

3, the next you can reload, and the syringe suction use 30 ml of water, each hole with 5ml (plus battery electric motor 10 ml) can be done (by the order, which is the reason why they buy the 30 ml syringe and a tube of water can add a battery, will not be mistaken if you get a 10 ml syringe, then you expect to increase the absorption of water, you know not added any hole, and where the holes did not increase.)

 

4, after addition of water can be covered with rubber caps and cotton wool, as is the recovery, do a good job can be covered after the cover, but to see the next step.

 

5 with a small screwdriver lights PVC glue in the lid and battery on a few clicks of the glue, and then you can cover, and the glue does not have much difficulty in avoiding the next opening, but may be too large rubber cap on the flow This tight rubber cap was originally exhaust can exhaust and the battery will explode, and Hehe.

 

6, install a good battery, put it aside for 10-24 hours and then recharge it, which would position the internal battery of the same electrolyte concentration. Finished charging, the battery capacity would be increased. I wish you good luck! Latitude D820 battery Latitude D830 battery

Lithium metal and water will play a rapid and drastic chemical was considered unsuitable as a Sony VGP-BPS2 Sony VGP-BPS2A. Bao geography has developed a “protected lithium electrode,” in order to solve this problem. Based in Berkeley, California, PO Geography (Polyplus), the company develops the use of ambient air, such as a battery cathode high energy light. Bao manufacturing company with an American partner for the U.S. government has developed a lithium metal battery time of the air, the battery is expected within a few years on sale. Bao Geography of the company also produces lithium-metal-ion rechargeable lithium-air, is now developing products to start with this battery-powered electric vehicles eventually extended the time between charges. In recent years from the plug-in hybrids to a laptop, with the increase of such devices in the energy needs for light, people are interested in the metal-air batteries, lithium is increasing. Yin and Yang electrodes of Li-ion batteries, made from materials of graphite, while the lithium-metal-air is a lithium metal anode is made solely by the cathode through the air may be. Lithium-Metal air batteries do not need access to equipment in high power density are needed to study, to be close to the energy density of the fuel cell. In theory, the greater energy density is greater than limit of 5000 watts per mile, or more than ten times the current density of energy lithium batteries. Because they are not necessary to load reactive cathode, the lithium metal-air batteries are very light. Lithium metal is “sacred battery materials,” Po Geography, Chief Technology Officer and founder Steven • Visco (Steven Visco) said. Sony VGP-BPS2B Sony VGP-BPS2C

 

IBM recently announced energy and transport networks will develop lithium-metal battery of ‘air. “Lithium-ion is very perfect, but the lithium metal can be won,” California-based CIMA city (Sylmar, CA) Union Kwame (Quallion) Battery Manufacturing Company President Paul • Beach (Paul Beach) said. However, the use of lithium metal electrodes as the battery has been problematic, mainly due to lithium metal and water reaction will play a quick, drastic chemical. “People keep thinking of lithium-air for several decades, but there is always the presence of water in the air Ah,” Visco said. Even just one exposure to traces of water, raw materials deteriorate quickly. Bao geography has developed a process they call “protected lithium electrode” products in order to solve this problem. This device consists of a rectangular plate of metal composition of lithium, the exterior with a knowing “lisicon” veneer ceramic electrolyte material covered. The solid electrolyte does not enter the water, but allow lithium ions to move through. In addition, a coating to prevent the electrolyte and lithium metal reacts. And finally, this device is similar to chip potatoes in a sack of rolled aluminum polymer peak. This provides seal waterproof laminated films, flexible and easy to bend, so use of contraction when the electrode will not cause tension. When the lithium metal electrode placed in water, lithium-ion release, with the oxygen dissolved in water or water itself is to take effect. Fabricated metals lithium-air equipment, equipped with an electrode gas diffusion which, with hearing aids used in the manufacture of zinc used in the metal of the Sony VGP-BPS8 Sony VGP-BPS8A looks like electrodes. And with the hearing aid batteries are different is that over time, these lithium-metal-air battery will not self-discharge. “You can put metal in the lithium-air resting on a shelf for months because of the thin layers of protection for the battery so that the normal course,” said Visco. But because of the high Lithium-metal energy spread, the battery life is also longer and lighter than the zinc-air batteries are much longer.

 

Bao Geography Society is currently working with the Monterey Bay Aquarium Research Institute, California (Monterey Bay Aquarium Research Institute) to work together to test the lithium metal water, the battery can afford to determine the actual conditions of use. Although the initial test provides a good result, but there is concern is the battery of marine microbes in the cut surface of the growth at the expense of operation of the battery. Bao Geography manufactured disposable batteries, using about 2 inches square, 3 mm thick lithium metal. This one-time close to current capacity Laptop Battery Rechargeable lithium-ion storage capacity, while the weight is only one fifth of lithium-ion Sony VGP-BPL8 Sony VGP-BPL8A. Bao Geography boasted, in conjunction with partners from the battery manufacturer at Po geography design electrode based on the contract will be for a government agency that produced undisclosed battery. Kwame associated company, said the treatment of lithium metal electrode can use the existing battery manufacturing Lithium-ion in many facilities. “Need some preventive measures to deal with materials, but nothing special stuff,” Beach said. Monterey Bay Aquarium Research Institute • Bellingham, chief technologist, James (James Bellingham) said that for underwater applications, the lithium metal has a “change” potential. Bellingham, as noted, most of the marine research took place in areas near the coast, because “the oceans are not blocked electricity to detect pieces filled with self-control devices Navigation Navy to monitor the load. Bellingham said that higher energy density batteries, can make the results of the monitoring of climate change on Earth became a better fate. Sony VGP-BPS9 Sony VGP-BPS9/B
