The common characteristics of all cells, lithium-ion battery is charged, contains a lithium electrode and charge transported by the lithium-ion cell. A big advantage of lithium-based cells is their high voltage terminal and a better power to weight ratio. Different types of recipes are available electrode materials, each voltage characteristics and other properties. Other factors affecting the nature and costs associated with the choice of the electrolyte and separator.
The choice of the separator is an important factor in both production costs and the safety of the cells. An interesting recent development is the ceramic separator stabbing Separion already used in the cells of the German battery maker Li-Tec. The separation stabbing resists high temperatures and can help to prevent the internal short circuit within the cell. This is a very important aspect, fully loaded cell, lithium-ion battery, unlike NiMH cells can not continue to accept these without damage, including risk of explosion. The other side of the coin is very high efficiency of the cell (90% to 95%). Safer species lithium iron phosphate (LiFePO4) cells A123 and Gaya, the price of around 10% lower energy density and voltage terminal.
