[0002] Automotive lithium batteries are high-energy-density batteries used to power electric and hybrid vehicles. They primarily store and release energy through the charging and discharging process of lithium ions between the positive and negative electrodes. Given the diverse operating environments of automobiles, automotive lithium battery heating films are used to heat and protect the batteries from excessively low temperatures.

[0003] Existing automotive lithium battery heating films typically include an outer film layer, a heating layer, an inner film layer, heating wires, and wires. The heating wires are placed inside the heating layer, which is located between the outer and inner film layers. The wires are connected to the heating wires, thereby allowing the inner film layer to adhere to the automotive lithium battery and enabling heating operations using the heating wires.
