Title: Method for producing electrode composite material

Abstract: An object of the present invention is to simplify the process of producing an electrode composite material. Disclosed is a method for producing an electrode composite material, comprising the steps of: preparing a material comprising Li, La, Ti and O and heating the material, wherein the composition ratio between Li, La and Ti of the material is in the range of a triangle having three vertices at LiO.sub.0.5:LaO.sub.1.5:TiO.sub.2=23:24:53, LiO.sub.0.5:LaO.sub.1.5:TiO.sub.2=5:36:59 and LiO.sub.0.5:LaO.sub.1.5:TiO.sub.2=8:28:64 in the LiO.sub.0.5--LaO.sub.1.5--TiO.sub.2 triangular diagram.
