摘要：PROBLEM TO BE SOLVED: To further increase the utilization ratio of activematerial.SOLUTION: An electrode manufacturing method of the present inventionincludes an electrode manufacturing step of heating a molded body of compositeparticles in which a lithium boron-containing oxide having a melting temperature lowerthan that of the active material particles and having lithium ion conductivity is

compounded with at least one of a particulate form and a layered form, at a temperatureequal to or higher than the melting temperature of the lithium boron-containing oxide toproduce an electrode. Before the electrode preparation step, composite particlepreparation step of preparing composite particles by complexing lithium boron-containing oxide on the surface of active material particles by applying compressive,shear and impact forces to particles of active material particles and lithium boron-containing oxide may be included. The composite particles may be composite particles 30in which the lithium boron-containing oxide particles 34 are dispersed and immobilized onthe entire surface of the active material particles 32.SELECTED DRAWING: Figure 1
