PURPOSE:To obtain high energy density, high potential, and good cycle performance by using a specific compound having good conductivity and large capacity as a positive active material. CONSTITUTION:A substance selected from compounds as indicated in the chemical formulas (1) to (5) is used as a positive active material. In the formulas, x<=1, z<y<=1, and m=n<=1. Lithium or lithium alloy capable of absorbing or desorbing lithium ion is used as a negative active material. A nonaqueous substance which is chemically stable to positive and negative active materials and in which lithium ion is movable for electrochemical reaction with the positive active material is used as an electrolyte. By this constitution, a battery having high energy density, high potential, and good cycle performance can be obtained. |
