Positive electrode material for lithium ion battery with nonaqueous electrolyte, and battery using the same |
摘要 |
An object of the present invention is to provide a positive electrode material for non-aqueous electrolyte lithium-ion battery which capable of discharging high output power and inhibiting cracking of secondary particle in the cyclic endurance at a high temperature. The above object can be attained by a positive electrode material for non-aqueous electrolyte lithium-ion battery of the present invention, characterized in that said material comprises secondary particles composed of primary particles of lithium nickel composite oxide containing the primary particles having different aspect ratios, and that at least a part of said primary particles having different aspect ratios are arranged so as to make the longitudinal direction (the long side direction) thereof oriented toward the center of the secondary particle. |
