PURPOSE:To enhance the charging/discharging cycle lifetime by using niobium pentoxide to pos. electrode and Al alloy to neg. electrode, and by using a non- aqueous solvent in which lithium perchlorate is dissolved as an electrolyte. CONSTITUTION:Lithium perchlorate is dissolved in a non-aqueous solvent containing aliphatic hydrocarbon having carbonate radicals, that is used as electrolyte. Examples of the non-aqueous solvent are propylene carbonate(PC), butylene carbonate(BC), and ethylene carbonate(EC). Aid solvents may also be used such as 1,2-dimethixyethane(DME), 2,2-diethoxyethane(DEE), and 1,2- ethoxymethoxyethane(EME). The Al alloy mentioned shall be a one to which Mn, Ag, Mg, In, etc., are added in order to increase the strength of Al and enhance Al solid phase diffusion. |
