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 provided by the present invention has a positive electrode having a current collector and a positive electrode composite layer provided on the current collector. The current collector contains a metal element A as a main component thereof. The positive electrode composite layer contains a two-phase compound containing lithium as a positive electrode active material. The positive electrode composite layer also contains as an additive a compound having a metal element B, in a composition thereof, that has a higher ionization tendency than the metal element A.
