Lithium-ion batteries have several vital components that store and release energy. These components include the anode, cathode, electrolyte, and separator. The anode is a vital part of a lithium-ion battery. It stores the lithium ions when the battery is charged. The most common material used for the anode is graphite.
Charging the battery forces the ions to move back across the electrolyte and embed themselves in the negative electrode ready for the next discharge cycle (Figure 1).
