A lithium-ion battery, or Li-ion battery or LIB belongs to a family of rechargeable battery types. Ronda began with cylindrical battery shape.
With different cathode materials, Li-ion battery is divided into 3 types of chemistry: LiCoO2 battery, LiMn2O4 battery and Li(NiCoMn)O2 battery.
Rechargeable Li-ion battery Cells' Features.
