Abstract
The invention provides a cover plate assembly and a battery containing the cover plate assembly. The cover plate assembly includes a cover plate body, a cover plate connector and an electrode terminal; the cover plate connector has an electrode hole penetrating the cover plate connector, and the electrode The terminal passes through the electrode hole and is insulated and sealed between the cover plate connector; the cover plate body has a through hole through the cover plate body, and the electrode terminal draws current through the through hole; the cover plate connector is sealed and connected with the cover plate body. The technical solution of the present invention can improve production efficiency, reduce production cost, especially high yield rate, good safety performance, and at the same time, the structure of the cover plate assembly of the present invention is firmly connected and has good sealing performance, which lays a solid foundation for the practical application and development of ceramic sealed batteries. foundation.
Description
technical field [0001] The invention relates to a cover plate assembly and a battery containing the cover plate assembly. Background technique [0002] Lithium-ion battery is an important product of new energy, which has the advantages of no pollution, high capacity and long cycle life. At present, lithium-ion power batteries, lithium-ion tool batteries, network energy and other fields. Lithium-ion batteries are made by winding or stacking the positive electrode sheet, diaphragm, and negative electrode sheet into the core, then putting the core into the cavity formed by the battery case and the sealed cover plate, injecting the electrolyte into the inside, and then sealing and forming. get. The sealing cover is an indispensable component of the lithium battery seal, and its safety, sealing, aging resistance, insulation, and the size of the space occupied in the battery are of great significance. In addition, the cover assembly occupies the entire A certain cost of lithium...
