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.
The electrolyte in a lithium-ion battery is the medium that carries the lithium ions between the anode and cathode. It can be a liquid, gel, or solid. Liquid electrolytes are most common and are usually made of lithium salt in an organic solvent. Solid electrolytes are being developed for safety reasons because they are less likely to leak.
Structure-property in Li-ion batteries are discussed by molecular orbital concepts. Integrity of electrodes is described using inter-atomic distances and symmetry. Internal reaction/band structure of active materials under cycling are emphasized. Chemical and structural stability of conventional cathode families are addressed.
Lithium-ion batteries work through a process called electrochemistry. This involves chemical reactions that produce electricity. Lithium ions move from the cathode to the anode when the battery charges through the electrolyte. Electrons flow through an external circuit to balance the charge. When the battery discharges, the process reverses.
