Abstract:
To provide a battery which can be suppressed in abnormal heat generation thereof and can be suppressed in ignition or smoking thereof.SOLUTION: A battery 100 comprises: a first current collector 3; a laminate which is arranged on a first region in a main surface of the first current collector 3; a layer which is arranged on a second region in the main surface of the first current collector 3; and a second current collector 1 which is opposite to the first current collector 3 with the laminate and the layer interposed between them, and is arranged on the laminate and the layer. The laminate includes: a first active material layer 4 which is arranged on the first region; an electrolyte layer 5 which is arranged on the first active material layer 4; and a second active material layer 2 which is arranged on the electrolyte layer 5. The layer includes at least one selected from a group consisting of PA, PI, PAI, aramid, PEI, PSF, PES, PET, PEEK, PTFE, PVDF, PP, and PE. A coefficient of thermal expansion of the layer is larger than that of the laminate.
