Title: ALL-SOLID STATE SECONDARY BATTERY AND METHOD FOR MANUFACTURING SAME
Abstract:
The present invention is a method for manufacturing an all-solid state secondary battery (10) composed of a plurality of provisional battery bodies (7, 7). The present invention includes: a step for forming each of a plurality of provisional battery bodies (7, 7) by pressing a laminate formed by stacking a positive-electrode mixture (2), a solid electrolyte (3), and a negative-electrode mixture (4) between a pair of electrode current collectors (1, 5); and a step for performing pressure molding in a state where the plurality of provisional battery bodies (7, 7) are overlaid such that the electrode current collectors (1, 5) face each other. Electrode current collectors having roughened surfaces are used as the electrode current collectors (1, 5) facing each other.
