PROBLEM TO BE SOLVED: To provide a composite electrode material and a method for producing the same.SOLUTION: A composite electrode material includes: a complex oxide coated with nano-sized carbon; fibrous carbon; and a binder. The electrode material is produced by a method which includes co-grinding an electrode active material and fibrous carbon, and adding a binder to the co-ground mixture to lower the viscosity of the mixture. The fibrous carbon is preferably vapor grown carbon fibers. The complex oxide is preferably selected from the group consisting of a sulfate, a phosphate, a silicate, an oxysulfate, an oxyphosphate and an oxysilicate of a transition metal and lithium, and a mixture thereof. LiFePO4, LiMnPO4, LiFeSiO4, SiO and SiO2 are preferred complex oxides. |
