PURPOSE:To increase capacity and reduce a drop of the capacity due to rapid charge and discharge by having a mixture consisting of the activated carbon of fixed specific area value and a metal oxide as a positive electrode activated material and using a specific electrolyte. CONSTITUTION:A composite consisting of the activated carbon having the specific area value of at least 600m<2>/g by a BET method and a metal oxide is made a positive activated material. A nonproton property organic solvent solution of a compound capable of generating ions able to be doped in a positive electrode activated material by electrolysis is used as an electrolyte. A substance, wherein intercalation or deintercalation of Li ions is possible, is used as the metal oxide. Especially, a transition metal oxide is desirable. Powdered activated carbon or the activated carbon in the shape of molded powder is used. 95/5-15/85 of a wt. ratio of activated carbon/metal oxide is desirable. LiI, LiCl, LiBF4, LiAsF6 and LiPF6 are used as the compounds for generating ions able to be doped in the positive electrode active material by electrolysis. |
