POSITIVE-ELECTRODE MEMBER AND METHOD FOR PRODUCING THE SAME |
摘要 |
A positive-electrode member for producing a nonaqueous electrolyte battery having a high discharge capacity and an excellent cycle characteristic, and a method for producing the positive-electrode member are provided. The positive-electrode member includes a positive-electrode collector composed of a metal; and a positive-electrode active-material layer (positive-electrode active-material portion) 10B that allows for electron transfer between the positive-electrode collector and the positive-electrode active-material layer 10B. The positive-electrode active-material layer 10B includes positive-electrode active-material particles 1 and a solid electrolyte 2 that fixes the particles 1. The contours of the particles 1 that are next to each other partially conform to each other. To produce such a positive-electrode member, a raw-material sol obtained by mixing positive-electrode active-material particles with substances that turn into a solid electrolyte through polycondensation by heating is applied to a positive-electrode collector, and the resultant member is heated and subsequently pressed. |
