PROBLEM TO BE SOLVED: To obtain a positive electrode plate for a nonaqueous secondary battery capable of increasing a bulk density to increase discharging capacity, and moreover preventing short-circuiting between electrode plates due to carbon powder. SOLUTION: Ink for a positive electrode mixture is manufactured by kneading lithium-containing double oxide powder (LiCoO powder): composed of the particle diameter mixed powder of powder having a mean particle diameter of 1-10μm, and powder having a mean particle diameter of 20-30μm, a conductive assistant: composed of carbon powder having a mean particle diameter of 0.1-10μm, and a binding agent. The positive electrode mixture ink is applied to a collector, and then dried to form a positive electrode mixture layer. The containing rate of powder, having a mean particle diameter of 1-10μm in lithium- containing double oxide powder, is to be 5-50wt.%, and carbon powder is contained 5-10wt.% to the positive electrode mixture. |
