Lithium ions are moved between the electrodes of a lithium-ion battery via an electrolyte between the anode and cathode. As lithium ions charge, they move from the cathode to the anode, and when they discharge, they move back to the cathode. Electricity can be produced from this movement of ions. A graphite anode is typically combined with a lithium cobalt oxide cathode. An organic solvent is used as an electrolyte.
