Description

Technical Field

[0001] The utility model belongs to the technical field of lithium batteries, and in particular relates to a novel lithium ion battery pole piece structure. Background Art

[0002] A pole piece is usually provided in a lithium-ion battery. The pole piece is a thin sheet composed of an active substance and a conductive material, and is responsible for storing and releasing electric charge. The existing lithium-ion battery pole piece structure includes a clamping rubber head, and an anti-slip installation threaded hole is provided on the surface of the clamping rubber head, and an upper fixing screw is threadedly connected to the anti-slip installation threaded hole through the threaded hole provided on the upper surface of the side fixing baffle plate at a position corresponding to the anti-slip installation threaded hole. The upper fixing screw passes through the outer surface of the side fixing baffle plate and is threadedly connected to the inside of the anti-slip installation threaded hole. This lithium-ion battery pole piece structure protects the pole piece connection protrusion through a protective shell, but the plug-in fixing head is prone to bending when subjected to external force, so the protection effect of the plug-in fixing head is poor.
