The embodiment of the invention relates to the technical field of lithium batteries, and provides a lithium battery cover plate assembly. The lithium battery cover plate assembly provided by the embodiment of the invention comprises a cover plate, a lower insulating spacer and a sealing rubber ring; a first sinking table is formed on the upper surface of the cover plate; a second sinking table isformed on the upper surface of the lower insulating spacer, and the lower insulating spacer is arranged under the cover plate; the sealing rubber ring is arranged in the second sinking table and makescontact with the lower surface of the cover plate, the lower insulating spacer, the sealing rubber ring and the cover plate are sequentially connected through a rivet, and the sealing rubber ring isextruded by the rivet to deform so as to be sealed between the lower insulating spacer and the cover plate. According to the lithium battery cover plate assembly provided by the embodiment of the invention, the single rivet is used for extruding to deform the sealing rubber ring so as to seal the cover plate and the lower insulating spacer, so that the structure of the cover plate is optimized, the production process is simplified, and the purpose of reducing the production cost is achieved.
Description
technical field [0001] The invention relates to the technical field of lithium batteries, in particular to a lithium battery cover assembly. Background technique [0002] With the development of the new energy industry, especially the rapid development of the new energy automobile industry, the use of lithium batteries is also increasing. Compared with traditional batteries, lithium batteries have the advantages of high energy density, high working voltage, light weight, small size, small self-discharge, no memory effect, long cycle life, fast charging, etc., and are more environmentally friendly than traditional batteries. Traditional batteries such as lead-acid batteries are gradually being phased out. However, with the rise in prices of various production raw materials, reducing the manufacturing cost of lithium batteries has become a problem that every lithium battery manufacturer must face and think about. [0003] Lithium batteries include cylindrical batteries and p...
