摘要： A bipolar storage battery that can prevent outward leakage of an electrolytic solution and reduction of mechanical strength by strongly joining plates each holding a cell member, thereby ensuring hermeticity of the inside of a cell and the mechanical strength, and also making the bipolar storage battery compact while reducing the number of components. The bipolar storage battery includes an internal frame unit including a bipolar plate in which a positive pole is provided on one surface and a negative pole is provided on an other surface, and an internal rim is provided in an outer edge of the bipolar plate. A plurality of the internal frame units are stacked and adjacent internal rims are welded to each other. A ratio of a width of the internal rim to a depth of welding between the rims is between 2.7 times and 16.0 times, inclusive.

摘要： A battery packaging material includes a substrate layer, a heat-fusible resin layer, a barrier layer arranged between the substrate layer and the heat-fusible resin layer, and a substrate protective layer as an outermost layer arranged on an outer side of the substrate layer. The substrate protective layer includes a binder resin 21, and wax, resin beads, and inorganic fine particles as solid fine particles. The solid fine particles project outward from a surface of the substrate protective layer to form a protrusion. In a plan view of the substrate protective layer, an area ratio of a portion of the protrusion having a height of 1 μm or more from a reference plane of an arithmetic average height Sa is 5% to 20%.
