Embodiment approach
[0026] As a specific embodiment of the present invention, a plurality of through holes 21 are punched on the surface of the battery pole pieces 2 clamped between the clamping plates 311, and the clamping plates 311 are made of elastic rubber material; through the through holes 21 The cooperation with the clamping plate 311 made of rubber material further enhances the firmness between the clamping plate 311 and the battery pole piece 2; during work, the through hole 21 of the battery pole piece 2 is punched out, so There is a flange remaining at the hole of each through hole 21, and after the flange is attached to the clamping plate 311 made of elastic rubber material and squeezed, the flange at the through hole 21 will sink into the clamping plate 311 , so that the sliding friction between the clamping plate 311 and the battery pole piece 2 is converted into static friction, and the firmness of the clamping plate 311 and the battery pole piece 2 is enhanced, thereby avoiding th...

The invention belongs to the technical field of lithium ion batteries, and particularly relates to a lithium ion battery pole piece structure which comprises a battery panel and a battery pole piece.A protection device is arranged on the battery pole piece; the protection device comprises a clamping base and a clamping block; one end of the battery panel is embedded into one end of the clamping base, the battery pole piece at one end of the battery panel penetrates through the clamping base and extends out of the other end of the clamping base, and clamping plates are symmetrically arranged in the clamping base; the section cutting surface of the clamping plates is triangular, one right-angle surface of the clamping plates is attached to the panel surface of the battery panel, the other right-angle surface of the clamping plates is attached to the battery pole piece, and the inclined surface of the clamping plates is attached to the clamping block; one end of the clamping block is embedded between the side wall of the clamping base and the clamping plate, and the other end of the clamping block is attached to the battery pole piece. The battery pole piece is protected through cooperation among the clamping base, the clamping plates and the clamping blocks.
Description
technical field [0001] The invention belongs to the technical field of lithium ion batteries, in particular to a lithium ion battery pole piece structure. Background technique [0002] Lithium-ion battery is a secondary battery (rechargeable battery, which mainly relies on lithium ions to move between positive and negative electrodes to work. During charging and discharging, Li + Intercalation and deintercalation back and forth between two electrodes: when charged, Li + It is deintercalated from the positive electrode, inserted into the negative electrode through the electrolyte, and the negative electrode is in a lithium-rich state; the opposite is true during discharge. [0003] When the lithium-ion battery is in use, the positive and negative electrodes exposed outside the battery board are thin, have a small elastic coefficient, and are prone to bending. After the bending fatigue is greater than that of the battery pole piece, the battery pole piece is prone to breakag...
