Power supply storage device with high heat dissipation performance

The utility model relates to the technical field of power sources, and particularly discloses a high-heat-dissipation power source storage device which comprises a shell, a power source assembly, a heat dissipation assembly and a layering assembly, a containing cavity is formed in the shell, the power source assembly, the heat dissipation assembly and the layering assembly are all arranged in the containing cavity, and the layering assembly divides the containing cavity into a plurality of containing cavities; the power supply assemblies can be placed in the different placing cavities respectively, the situations that the local temperature is too high and the power supply assemblies are fused due to the fact that the placing positions of the power supply assemblies are too concentrated and heat is concentrated at the same position are avoided, the power supply assemblies and the heat dissipation assemblies are arranged in a distributed mode, heat in the containing cavities is evenly dispersed, heat dissipatio
