The aggregated lithium ions are thus deposited on the surface of the electrodes, which causes the reduction of the battery capacities. Furthermore, the lithium plating exists in the form of dendrite, which may penetrate the separators, and result in the internal short-circuit [83] .
These factors make it an attractive prospect for batteries. However, being a Group I metal, lithium is highly reactive and therefore it is necessary to use a non-aqueous electrolyte. Lithium batteries generally have lithium metal (or alloy) as the anode but show an extensive range of chemistries for the cathode and the electrolyte.
