Title: POSITIVE ELECTRODE ACTIVE SUBSTANCE FOR HIGH-PERFORMANCE LITHIUM ION BATTERY AND METHOD FOR PRODUCING POSITIVE ELECTRODE ACTIVE SUBSTANCE
Abstract:
[Problem] To provide a lithium nickel metal compound oxide powder that is low-alkali and has excellent cycle properties, a lithium ion battery positive electrode active substance containing the powder, a lithium ion battery positive electrode that uses the active substance, and a lithium ion battery having the positive electrode. [Solution] A lithium nickel metal compound oxide that is low-alkali and has excellent cycle properties is successfully produced by controlling the crystal grain size and composition ratio in a lithium nickel metal compound oxide powder.
