The invention provides a novel explosion-proof lithium battery top cover plate. The novel explosion-proof lithium battery top cover plate comprises a base plate, a top plate, upper anode plastic, upper cathode plastic, an anode seal ring, a cathode seal ring, an anode column, a cathode column, an anode lead sheet, a cathode lead sheet and multi-level explosion-proof devices. The top plate is fixed to the base plate, the cathode column sequentially penetrates the anode seal ring, the base plate, the top plate and the upper anode plastic, and the anode column sequentially penetrates the cathode seal ring, the base plate, the top plate and the upper cathode plastic. The novel explosion-proof lithium battery top cover plate has advantages of low cost, convenience in use and high safety.
