Abstract: A battery includes an outer packaging and a power generating element that contains a sulfur-based material and is included in the outer packaging and disposed in the inside of the outer packaging. The outer packaging includes a communicating port, a hydrogen sulfide eliminator, and an exhausting unit. The communicating port communicates between the inside and the outside of the outer packaging. The hydrogen sulfide eliminator and the exhausting unit are disposed in the communicating port. The exhausting unit introduces hydrogen sulfide generated caused by the sulfur-based material to the communicating port. The hydrogen sulfide eliminator eliminates the hydrogen sulfide introduced by the exhausting unit to the communicating port.

Abstract: A battery including a positive electrode layer and a negative electrode layer is provided. The positive electrode layer includes a positive electrode current collector, a positive electrode active material layer, and a positive electrode-side solid electrolyte layer; the positive electrode active material layer is arranged in contact with the positive electrode current collector in a region smaller than that thereof; the positive electrode-side solid electrolyte layer is arranged in contact with the positive electrode current collector and the positive electrode active material layer in the same region as that of the positive electrode current collector; the negative electrode layer has the structure similar to that of the positive electrode layer. Since the positive and negative electrode layers are laminated to each other, the positive electrode active material layer faces the negative electrode active material layer with the positive and negative electrode-side solid electrolyte layers provided therebetween.
