Anti-extrusion lithium battery

The utility model provides an anti-extrusion lithium battery which comprises a battery assembly, and the battery assembly comprises a lithium battery pack; two metal frame bodies which are symmetrical up and down are arranged on the outer side wall of the lithium battery pack, and wooden frame bodies are fixedly connected to the inner side walls of the metal frame bodies. According to the utility model, due to the pressure resistance and extensibility of metal and the hard resistance of wood for resisting external force compression deformation destruction, the hard extrusion resistance of the exterior of the lithium battery pack is increased, and the plurality of convex damping pads have a buffering effect on the inner wall of the wood frame body and the exterior of the lithium battery pack, so that the service life of the lithium battery pack is prolonged. The two adjacent lithium batteries are isolated and protected by the triangular pad, the influence on the other adjacent lithium battery after the single
