Abstract
Provided is a method of producing a nitrided lithium-transition metal compound oxide having a rock-salt layer structure or a spinel structure, including: preparing a raw material composite that has a raw material containing lithium, transition metal, and oxygen and a nitriding agent that is expressed by a following General Formula (1) and is solid or liquid at room temperature (25° C.); and synthesizing the nitrided lithium-transition metal compound oxide by firing the raw material composite to nitride the raw material.R1, R2, and R3 are independent of each other and are each a functional group having at least one of carbon (C), hydrogen (H), oxygen (O), and nitrogen (N).
