Battery and electric device

Abstract

This application discloses a battery and an electrical device, belonging to the field of battery technology. It includes: a core having a curved portion; and a liquid storage structure capable of absorbing electrolyte. The liquid storage structure and the core are bonded and fixed together, and the liquid storage structure covers the outer peripheral surface of the curved portion. In this embodiment, the above arrangement has the beneficial effect of preventing the core's performance from degrading due to electrolyte drying, thus extending the battery's lifespan. Simultaneously, the bonding and fixing of the liquid storage structure to the core enhances the overall rigidity of the battery cell, preventing structural loosening caused by repeated expansion and contraction of the core, further improving the battery's reliability.
