Document Type and Number:
Japanese Patent JP4056183
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To obtain a non-aqueous electrolytic secondary cell with high energy density, in which short-circuiting by dendrites is not caused and a cycle life is excellent. SOLUTION: The non-aqueous electrolytic secondary cell is an active material having A-phase expressed in the formula 1: M1aM2 and having composition satisfying 0.25<=a<3 and B-phase expressed in the formula 2 M1bM2 and having composition satisfying 1<=b and a
