摘要： A rechargeable battery includes at least a porous base (10), a first electrode layer (11), an ionic conductor layer (13), and a second electrode layer (12). The porous base (10) includes a conductive framework (1). The framework (1) has a three-dimensional network structure. On at least part of a surface of the framework (1) in the interior of the porous base (10), the first electrode layer (11), the ionic conductor layer (13), and the second electrode layer (12) are stacked in this order. The first electrode layer (11) and the second electrode layer (12) have opposite polarities.

摘要： A lithium-ion secondary battery (100) includes a wound electrode body (80), a nonaqueous electrolyte, and a box-shaped case (50). The wound electrode body includes a positive electrode (10), a negative electrode (20), and a separator (40). The box-shaped case contains the wound electrode body and the nonaqueous electrolyte. The wound electrode body includes a starting-end-side negative electrode remainder portion (22) provided in a winding-direction starting end portion (81) of the wound electrode body. The winding-direction starting end portion exists at a winding center side. The starting-end-side negative electrode remainder portion protrudes toward the winding center side along a winding direction beyond the positive electrode. A surplus nonaqueous electrolyte exists in a gap between the wound electrode body and the box-shaped case. The starting-end-side negative electrode remainder portion is positioned in a region where the surplus nonaqueous electrolyte exists, when the lithium-ion secondary battery is disposed in a predetermined posture.
