Lithium batteries have the advantages of high energy density, long cycle life, light weight and portability, and are widely used in fields such as mobile devices, electric vehicles, and energy storage systems.

[0003] Since the voltage of a single lithium battery is relatively low, multiple lithium batteries generally need to be connected in series. When multiple lithium batteries are connected in series, they need to be placed in a housing for storage. The currently common lithium battery housing structure is generally composed of a single-layer baffle, and its puncture resistance performance is poor during use, which will affect the use safety of the lithium battery housing structure.

Lithium battery blocks are equidistantly installed inside the inner housing. A convex top cover is installed on the top of the outer housing. A wire chamber is arranged on the inner top of the convex top cover. Handles are symmetrically arranged at the top of the convex top cover. Wiring ports are symmetrically arranged on one side edge of the top of the convex top cover.

Ventilation openings are opened in the middle of the bottom end and both sides of the U-shaped support plates.

[0008] As a preferred technical solution of the lithium battery housing structure of the utility model, the inner wall length of the U-shaped support plate is the same as the width of the inner housing, and the distance between two corresponding U-shaped clamping plates is the same as the length of the inner housing.

[0009] As a preferred technical solution of the lithium battery housing structure of the utility model, a plurality of heat dissipation holes are opened on the outer surface of the inner housing.
