The invention provides a high-safety battery cover plate, which comprises a substrate, a positive electrode insulation pad, a negative electrode insulation pad, a positive electrode column, a negativeelectrode column, a positive electrode rivet and a negative electrode rivet, wherein the substrate is provided with a positive electrode insulation groove and a negative electrode insulation groove,the positive electrode insulation pad and the negative electrode insulation pad are respectively embedded in the positive electrode insulation groove and the negative electrode insulation groove, thepositive electrode column and the negative electrode column are respectively embedded in a positive electrode groove and a negative electrode groove, the positive electrode rivet comprises a first base, the first base is positioned below the positive electrode insulation groove and is provided with a first rivet sequentially penetrating through a first assembling hole, a third assembling hole anda fifth assembling hole, the negative electrode rivet comprises a second base, and the second base is located below the negative electrode insulation groove and provided with a second rivet sequentially penetrating through a second assembling hole, a fourth assembling hole and a sixth assembling hole. According to the invention, the convex design of the traditional cover plate pole is changed intothe concave design, so that the possibility of short circuit caused by contact between the anode and the cathode of the battery is obviously reduced.
Description
technical field [0001] The invention relates to the technical field of lithium batteries, in particular to a high-safety battery cover plate. Background technique [0002] At present, ordinary lithium batteries adopt a design with convex poles, and with the popularity of this design, the corresponding battery assembly and welding technologies are also becoming mature. However, the protruding design of the poles also brings many safety hazards: first, if the batteries are stacked adjacent to each other without the help of external moulds, once one of the batteries falls sideways, the positive and negative poles will be directly Contact the aluminum shell of the battery to form a short circuit; secondly, when a metal object falls between the positive and negative poles, it will also cause a short circuit of the battery. [0003] Lithium-ion batteries have always been favored by everyone because of their high energy density. However, once a lithium-ion battery is short-circuit...
