NOVELTY - The utility model claims a single lithium ion battery with high efficiency and uniform heat dissipation, comprising a battery shell, a top cover; a winding core placed in the battery shell and integrally welded with the top cover; further comprising a U-shaped graphene heat conducting film and a U-shaped polypropylene binding strip located in the battery shell and tightly attached to the surface of the winding core; the inner surface of the U-shaped graphene heat conducting film is tightly attached to the surface of the winding core; the outer surface clings to the inner surface of the battery shell; the inner surface of the U-shaped polypropylene binding belt clings to the surface of the winding core; the outer surface clings to the inner surface of the battery shell. The monomer lithium ion battery internal heat of the utility model can be quickly and uniformly conducted to the battery surface, relieving the battery internal temperature gradient, preventing the heat accumulation caused by battery performance attenuation and safety trouble, and will not increase the burden and risk of the radiating system.
