Abstract

A cathode material which does not easily deteriorate when used in batteries, a method for producing cathode materials, a cathode, and a lithium ion battery are provided. A cathode material including a cathode active material, in which the cathode active material is expressed by Li 1+x A y D z PO 4 (here, A represents one or more metal elements selected from the group consisting of Co, Mn, Ni, Fe, Cu, and Cr, D represents one or more metal elements selected from the group consisting of Mg, Ca, Sr, Ba, Ti, Zn, B, Al, Ga, In, Si, Ge, Sc, Y, and rare earth elements, 0<x<1, 0<y<1, 0¤z<1.5, and 0.9<y+z¤1), and, in thermogravimetric analysis in an inert gas atmosphere, when a temperature is increased in a temperature range from 100°C to 300°C at a temperature-increase rate of 10°C/minute, a weight loss ratio in the temperature range is 0.3% by weight or less.
