POSITIVE ELECTRODE MATERIAL FOR ELECTRICAL DEVICE, AND ELECTRICAL DEVICE PRODUCED USING SAME

摘要

[Summary] [Problems to be Solved] Provided is a positive electrode material for an electrical device, which has high capacity and improved initial charge-discharge efficiency. [Means for Solving the Problem] Disclosed is a positive electrode material for an electrical device, which is represented by the formula (1):
€ƒ€ƒ€ƒ€ƒ€ƒ€ƒ€ƒ€ƒaLi[Li 1/3 Mn 2/3 ]O 2 €¢ (1-a)Li[Ni x Co y Mn 1-x-y ]O 2 €ƒ€ƒ€ƒ€ƒ€ƒ(1)
(wherein, 0 < a < 1, 0 < x < 0.5, and 0 < y < 0.3) and satisfies the relational expression: 2x + y < 1.
