摘要： A flat nonaqueous secondary battery with improved reliability is provided. The flat nonaqueous secondary battery (1) includes an electrode assembly disposed in a space formed by an exterior case (2) and a seal case (3). The electrode assembly includes a plurality of positive electrodes (5) and a plurality of negative electrodes (6) alternately stacked upon each other and a separator (7). The separator (7) has a joint (7c) formed by welding together at least a portion of its periphery. When the separator (7) and the positive electrode (5) are measured along a cross section in their thickness direction, the ratio A/B of the shortest distance A between the end of the joint (7c) of the separator (7) facing the positive electrode (5) and the outer periphery of the positive electrode (5) sandwiched by the separator (7) to the thickness B of the positive electrode (5) is not smaller than 1.

摘要： A main object of the present disclosure is to provide an all solid state battery including a dispersant-containing layer with good solid electrolyte dispersibility. The present disclosure solves the above problem by providing an all solid state battery comprising a cathode layer, an anode layer, and a solid electrolyte layer disposed between the cathode layer and the anode layer, and at least one of the cathode layer, the anode layer, and the solid electrolyte layer is a dispersant-containing layer including at least a solid electrolyte and a dispersant, an amine value of the dispersant is 20 mgKOH/g or more and 200 mgKOH/g or less, a weight-average molecular weight of the dispersant is less than 1,500,000 g/mol, and a proportion of the dispersant in the dispersant-containing layer is 0.1 weight % or more and 20 weight % or less.
