High-capacity lithium-ion battery cells to power notebooks and electric vehicles

Panasonic has announced the development of two new 18650-type (18 mm in diameter, 65 mm in height) high-capacity lithium-ion battery cells for laptop computers and environmentally-friendly energy technologies.

The two battery cells power laptops and electric vehicles, when used for the module these new battery cells can also serve as a high-energy storage system for clean energy technologies including household photovoltaic systems and fuel cells.

The newly-developed high-capacity 3.4 Ah and 4.0 Ah lithium-ion battery cells have an improved nickel based positive electrode, and the 4.0 Ah cell uses a silicon based alloy for the negative electrode instead of carbon.

Lithium-ion based storage systems are high compact and lighter than conventional storage systems using other types of rechargeable battery cells, high hopes are placed on the practical application of lithium-ion storage systems. The increasing range of applications for storage systems also provide high levels of capacity, output, reliability and safety, along with high cost performance.
