Lithium-ion Battery. A lithium-ion battery, also known as the Li-ion battery, is a type of secondary (rechargeable) battery composed of cells in which lithium ions move from the anode through an electrolyte to the cathode during discharge and back when charging.. The cathode is made of a composite material (an intercalated lithium compound) and defines the name of the …
