A typical lithium-ion battery contains: the cathode made of LiCoO2, the anode made of lithiated graphite, the separator and charge collectors.
The review paper delves into the materials comprising a Li-ion battery cell, including the cathode, anode, current concentrators, binders, additives, electrolyte, separator, and cell casing, elucidating their roles and characteristics.
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 anode is usually made out of porous lithiated graphite. The electrolyte can be liquid, polymer, or solid. The separator is porous to enable the transport of lithium ions and prevents the cell from short-circuiting and thermal runaway. Chemistry, performance, cost, and safety characteristics vary across types of lithium-ion batteries.
