Description

Technical Field

[0001] The utility model relates to the technical field of battery assembly components, in particular to a lithium battery compression protection structure. Background Art

[0002] Lithium batteries use lithium metal or lithium alloys as anode materials and a non-aqueous electrolyte solution. They are widely used due to their high energy density per unit volume. However, they are inherently unsafe and are prone to spontaneous combustion or explosion when damaged by pressure. Therefore, they often require external pressure-resistant protective structures.

[0003] Existing lithium battery pressure protection structures still have the following problems when in use: most of them are equipped with a pressure-resistant frame on the outside of the lithium battery, and the pressure-bearing structure of the frame usually adopts a hollow frame or solid plate structure design. However, the pressure-bearing capacity of the hollow frame pressure-bearing structure is average, and although the pressure-bearing capacity of the solid plate pressure-bearing structure is good, the solid plate itself has a large weight, which is not conducive to layout. At the same time, since the lithium battery is arranged inside it, it is not conducive to air circulation, and thus not conducive to the heat dissipation of the internal lithium battery.
