(CN218160457-U) NOVELTY - The utility model relates to the technical field of battery, specifically claims a self-heating battery current collector, comprising a heat generating graphene on the base material; the first conductive belt and the second conductive belt are oppositely arranged on the two sides of the surface of the base material and contact with the graphene heat layer; the packaging layer is covered on the base material, forming a closed interlayer with the base material; the closed interlayer completely covers the first conductive belt, the second conductive belt and the graphene heat layer; The current collecting conductor layer is coated on the outer surface of the base material far away from the graphene by coating the current collecting conductor layer on the outer surface of the base material graphene the heat generating layer, heating with graphene heat emitting layer, making it reach the technical effect of large area of the heating sheet under the condition of small heating space, making the heating film heat less than the power, it can heat for a long time under the low voltage and low current state, it is good for maintaining the best equalization temperature needed by the solid state battery for a long time, at the same time, ensuring the current effect of the battery current collection. DETAILED DESCRIPTION - INDEPENDENT CLAIMS are included for: (1) a self-heating electric core; (2) a self-heating battery. DESCRIPTION OF DRAWING(S) - The drawing shows an enlarged view of the self-heating battery current collector. 100Substrate 200Graphene heat generating layer 300First conductive strip 700Packaging layer 800Current collecting conductor layer
