The rechargeable lithium ion battery cell is the gasoline of the 21st century. Compared with traditional battery technology, lithium-ion battery cells charge faster and last longer, higher power density can achieve longer battery life and can be recycled.
Vodno as a china based lithium ion battery cell manufacturer in china, we offera variety of different brands lithium ion cell，including China, korean and Japan brands. All brands and different sizes of li ion cells can be assembled into lithium ion battery packs. 18650 and 21700 battery cells are typical type for using to make battery pack for widely electrical equipment.
There are five types of Li-Ion cells on current market based on chemistry of cathode materials. Please see the table below to see the details of each type cell.
