An electric vehicle battery is a rechargeable battery used to power the electric motors of a battery electric vehicle or hybrid electric vehicle. They are typically lithium-ion batteries that are designed for high power-to-weight ratio and energy density. Compared to liquid fuels, most current battery technologies have much lower specific energy. This increases the weight of vehicles or reduces their range. Li-NMC batteries using lithium nickel manganese cobalt oxides are the most common in EV. From Wikipedia
