Lithium ion cell

Consists of graphite anode and lithium cobalt oxide cathode. Polymer electrolyte used in cathode, silicon electrode used in anode.
Anode: LixC -> xLi++xe-+C(s)
Cathode: Li1CoO2+xLi++xe- -> Lix+1CoO2

This cell has higher energy density (3 times less weight) in comparison to lead acid cells. In addition, it also generates 3.7V per cell in contrast to 2V per cell for lead acid cells.

The cell has low memory, meaning that if you partially discharge the cell and recharge, the cell will recharge more completely.

In addition, it has faster recharge in contrast to lead acid cells.
