COATED LITHIUM-NICKEL COMPOSITE OXIDE PARTICLES, AND METHOD FOR PRODUCING COATED LITHIUM-NICKEL COMPOSITE OXIDE PARTICLES |
摘要 |
Provided are: superior coated lithium-nickel composite oxide particles which have an environmental stability that enables suppression of the occurrence of impurities due to absorption of moisture or carbon dioxide, which have high adhesion that prevents a coating layer from readily separating, and which have lithium ion conductivity; and a method for producing such particles. Provided is a method for producing coated lithium-nickel composite oxide particles, the method being characterized by contacting a cyclic siloxane with the surfaces of nickel-based lithium-nickel composite oxide particles to form surface coats. The particles have high adhesion to a coating layer and as a compound can suppress the permeation of moisture and carbon dioxide, and also have lithium ion conductivity. It is therefore possible to provide coated lithium-nickel composite oxide particles that are excellent for use in lithium ion cells. |
