Li-Ni COMPOSITE OXIDE PARTICLE POWDER AND PROCESS FOR PRODUCING SAME, AND NON-AQUEOUS ELECTROLYTE SECONDARY BATTERY |
摘要 |
The present invention provides lithium composite compound particles having good high-temperature storage property and excellent cycle characteristics as an active substance for a non-aqueous electrolyte secondary battery, and a secondary battery using the lithium composite compound particles. The Li-Ni composite oxide particles for a non-aqueous electrolyte secondary battery according to the present invention have a BET specific surface area of 0.05 to 0.8 m 2 /g; an atomic ratio (Ma/Ni) of a concentration of an amphoteric metal to a concentration of Ni on an outermost surface of the respective Li-Ni composite oxide particles is 2 to 6; and the concentration of the amphoteric metal on the outermost surface of the respective Li-Ni composite oxide particles is higher than a concentration of the amphoteric metal at a position spaced by 50 nm from the outermost surface toward a center of the respective Li-Ni composite oxide particles. |
