The cell which is used in Hybrid vehicles,

• Lead storage battery

• Li-ion battery

• Solar cell

• Ni-Metalhydride battery

LiPo batteries

• Can't recharge and reuse multiple times.

• Can recharge and reuse multiple times

• Can use only once.

• Can be used 3 to 4 times by recharging.

The cell potential can be measured as

• E_Cell = E_A - Ec

• E_Cell = E_A + E_C

• E_Cell = E_C - E_A

• E_Cell = E_C + E_A
