A battery according to an aspect of the present disclosure includes: a positive electrode, a negative electrode, a positive electrode tab electrically connected to the positive electrode; a negative electrode tab electrically connected to the negative electrode; a positive electrode tab tape covering the positive electrode tab: and a negative electrode tab tape covering the negative electrode tab. In the battery described above, at least one tab tape of the positive electrode tab tape and the negative electrode tab tape has a multilayer structure in which an adhesive layer and a substrate layer primarily formed from an organic material are laminated in this order from an electrode tab side, and the adhesive layer contains an adhesive material and a reactive material which generates an endothermic reaction at a temperature lower than a heat resistance temperature of the organic material.

A battery packaging material has an excellent ink printing characteristic on a base-layer-side surface. This battery packaging material has a laminated body formed by sequentially stacking at least a base layer, a metal layer, and a sealant layer, with the wet tensile strength of the surface of the base layer being 32 mN/m or greater.

The present disclosure provides batteries that have a reduced risk or no risk of gastrointestinal damage in a conductive aqueous environment, such as when accidentally swallowed. The batteries of the present disclosure advantageously stop producing significant current flow shortly after contact with a conductive aqueous medium, including the conductive aqueous medium of a wet tissue environment such as that found in the GI tract. The present disclosure further provides multi-layered laminate materials useful for manufacturing such batteries and methods for making the batteries. The batteries are, in some embodiments, 3 V or 1.5 V coin or button cell-type batteries.
