NOVELTY - The utility model claims a self-heating battery, comprising: a heating sheet and an electric core set at two sides of the heating sheet, the heating sheet comprises a graphene sheet, a lug and an insulating film set at two sides of the graphene sheet. The self-heating battery based on graphene sheet provided by the utility model has high electro-thermal conversion efficiency (near 100 %), uniform heating surface, light quality and flexible curling and so on because the graphene heating film; it can realize fast and uniform heating in the battery without loss of battery energy density. Therefore, the battery can release more capacity and energy at low temperature.
