Abstract
To provide: coated nickel-based lithium-nickel composite oxide particles which are able to be handled in the atmosphere and enable the achievement of a coating film of a lithium ion conductor having no adverse effects on battery characteristics; and a method for producing the coated nickel-based lithium-nickel composite oxide particles. A method for producing coated nickel-based lithium-nickel composite oxide particles, which comprises: an organic compound radicalization step wherein a radicalized organic compound is obtained by introducing an organic compound having 8 or less carbon atoms into a reaction gas, which has been excited into a plasma in the atmosphere, together with a carrier gas and radicalizing the organic compound; and a coating step wherein the surface of each nickel-based lithium-nickel composite oxide particle is covered with a coating film that contains an organic compound of a polymer or copolymer by bringing the radicalized organic compound into contact with the surfaces of the nickel-based lithium-nickel composite oxide particles.
