Battery and electronic device

The embodiment of the utility model relates to the technical field of batteries, and particularly discloses a battery which comprises a shell, an electrode assembly, a first bonding piece and a second bonding piece, a containing cavity is defined by the shell. The electrode assembly is arranged in the accommodating cavity. The first bonding piece comprises a first adhesive face and a first non-adhesive face which are arranged oppositely. The second bonding piece comprises a second adhesive surface and a third adhesive surface which are opposite to each other. Wherein the first viscous surface is adhered to the outer surface of the electrode assembly, the second viscous surface is adhered to the first non-viscous surface, and the third viscous surface is adhered to the inner surface of the shell. In the application, the first bonding piece and the second bonding piece can utilize the displacement between the first bonding piece and the second bonding piece to consume a part of kinetic energy, so that the force
