ABSTRACT:
A nonaqueous electrolytic secondary cell has an anode of an active material represented by Li.sub.x MO.sub.2 (M represents a material selected from the group consisting of Ni, Co, Fe, Mn, V, and Mo), an anode 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 LiBF.sub.4, LiPF.sub.6, and LiAsF.sub.6, into a mixture of 50.about.60 volume % of a mixture of cyclic carbonate and cyclic ester, 20.about.40 volume % of chain carbonate, and 10.about.25 volume % of chain ester.
