PROBLEM TO BE SOLVED: To provide a composite electrode material, coated with a solid electrolyte for inhibiting the reaction of an electrode material with an electrolyte and a nonaqueous secondary battery which is superior in safety and reliability. SOLUTION: After an electrode material powder, capable of reversibly doping or dedoping lithium, is dispersed in a solution consisting of a solid electrolyte or a solid electrolyte precursor dissolved in a solvent, the surface of the electrode material powder is coated uniformly with the solid electrolyte in a liquid or gas phase, capable of dissociating the solid electrolyte or the solid electrolyte precursor, while maintaining dispersed condition. |
