[0003] At present, after a long period of use of the existing lithium battery, the pole piece on the lithium battery is prone to corrosion, resulting in poor contact. The pole piece is fixed on the lithium battery and is not easy to disassemble for replacement. Only the entire lithium battery can be replaced. , increasing the loss

The invention discloses a lithium ion battery pole piece rapid installation structure with a simple structure. The structure comprises a lithium ion battery body and a pole piece installed on the lithium ion battery body; the top of the lithium ion battery body is provided with an annular groove, and the outer side of the edge of the top of the lithium ion battery body is provided with an annular step; the left side wall and the right side wall of the annular step are each provided with a containing groove, an extrusion piece is embedded in the annular groove, the extrusion piece comprises a limiting ring block and an extrusion pad, the outer side of the pole piece body is sleeved with the limiting ring block and the extrusion pad, and the left side and the right side of the limiting ring block are each provided with a threaded hole; and the edge of the top of the lithium ion battery body is sleeved with a protective sleeve. The installation structure between the pole piece and the lithium ion battery body is simple, installation is rapid and convenient, installation is stable and firm, meanwhile, the pole piece can be detached from the lithium ion battery body to be replaced, the whole lithium ion battery does not need to be replaced, and losses are reduced.
Description
technical field [0001] The invention relates to the field of lithium-ion batteries, in particular to a quick-installation structure for lithium-ion battery pole pieces with a simple structure. Background technique [0002] Lithium-ion batteries belong to secondary batteries in the classification of batteries, also known as storage batteries or rechargeable batteries. Lithium-ion batteries are developed from lithium batteries. The positive electrode material of lithium battery is manganese dioxide or thionyl chloride, and the negative electrode is lithium. In a battery, lithium ions move from the negative electrode to the positive electrode during discharge and back during charge. In contrast to metallic lithium used in non-rechargeable lithium batteries, lithium-ion batteries use intercalated lithium compounds as electrode materials. The three main functional components of a lithium-ion battery are the positive and negative electrodes and the electrolyte. The negative el...
