1. A lithium battery, comprisinga cathode plate and an anode plate;

  • a separator disposed between the cathode plate and the anode plate to define a reservoir region; and

    an electrolyte filled in the reservoir region,wherein a thermal protective film is provided to cover a material of the cathode plate or the anode plate, and when a battery temperature rises over an onset temperature of the thermal protective film, the thermal protective film undergoes a crosslinking reaction to inhibit thermal runaway, thereby preventing combustion or an explosion of the lithium battery, wherein the onset temperature is between about 80°

    C. and 280°

    C.
