摘要： This application relates to a heating assembly, a battery, and an electrical device. A heating sheet is affixed to a surface of a battery cell to heat the battery cell. When the battery cell thermally expands, cracks can break under an expansion force of the battery cell, so that the heating sheet deforms synchronously with the battery cell to prevent the heating sheet from being detached from the battery cell, thereby improving the efficiency of the heating sheet in heating the battery cell.
