Panasonic announced the development of the current used in computers, “18650″ size lithium-ion rechargeable batteries, high-performance products. Mass production was in December 2009.
The company said it plans in the future by connecting multiple 18650 size battery, it also can be used for domestic battery and EV (electric vehicle). If you are using the newly developed VGP-BPS2 battery, such as for the EV, can be the quantity of batteries with less distance to ensure its endurance.
A new battery “NCR18650A” In addition to cathode material with the original product “NCR18650″ use the same type of material other than nickel, as a security technology is also being equipped with heat-resistant layer between the anode (HRL: Heat Resistance Layer). HRL is configured with the diaphragm separately. The new VGP-BPS2A battery improved the original cathode materials and safety technology, as 18650 size battery to achieve the industry’s high capacity (3.1Ah).
Voltage is the same as the original is still the same as 3.6V, but the volume energy density by 620Wh / L increased to 675Wh / L. Therefore, the current capacity increased from 2.9Ah to 3.1Ah, battery capacity from the 10.4Wh raised to 11.2Wh. Weight from 44g to 44.5g around about.
