▎ 摘 要
NOVELTY - The battery has an outer housing, an inner core and a sealing cover. The outer housing and the sealing cover are matched to form a sealed cavity for placing the inner core of the battery and includes a graphene heating film (110), which wraps the inner core of the electric core. The graphene heating film is energized to generate heat for heating the inner core of the battery. The graphene heating film includes a substrate, a first power supply line (111), a second power supply line (112), a conductive tape and a graphene heating material. The substrate is coated with a graphene heating material. USE - Self-heating cell battery. ADVANTAGE - The cell active material heats up quickly and the preheating time is short, which is beneficial to quickly increase the power battery capacity and discharge rate, thus, improves the low temperature performance of the power battery. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for a method for making the self-heating cell battery. DESCRIPTION OF DRAWING(S) - The drawing shows a schematic view of the self-heating cell battery.
