A nonaqueous electrolytic secondary cell has an anode of an active material represented by LixMO2 (M represents a material selected from the group consisting of Ni, Co, Fe, Mn, V, and Mo), a cathode of a carbon material which can be doped or undoped with lithium, and an electrolyte produced by dissolving an electrolytic material selected from the group consisting of LiBF4, LiPF6, and LiAsF6, into a mixture of 50 - 60 volume % of a mixture of cyclic carbonate and cyclic ester, 20 - 40 volume % of chain carbonate, and 10 - 25 volume % of chain ester. |
