The fifth generation of rechargeable batteries, lithium metal batteries, was introduced in 1996 and offer superior safety, specific capacity, self-discharge rate, and performance-price ratio to lithium-ion batteries.

[0003] The lithium battery steel shell is a shell installed on the outside of the lithium battery, which can effectively protect the lithium battery and provide sufficient strength support.

[0004] Although the existing lithium battery steel shell can provide a certain degree of protection for lithium batteries, the entire shell needs to be disassembled when placing and replacing the battery. The operation is cumbersome and difficult, making it inconvenient to maintain or replace it, which increases the time and cost of maintenance. Utility Model Content

[0005] The purpose of the utility model is to solve the shortcomings of the prior art that the entire shell needs to be disassembled when replacing the battery, which is cumbersome and difficult to operate, inconvenient to maintain or replace, and increases the time and cost of maintenance, and to propose a lithium battery steel shell.

[0017] The battery pack is then released from the outer casing and replaced with a new one. When the battery pack is replaced, the handles are rotated and snapped into place in the slots. The spring sheet in the slot locks the handles, preventing the handles from falling off. When the battery pack needs to be repaired or replaced, there is no need to disassemble the entire outer casing. Instead, the battery pack can be easily removed to perform necessary maintenance or replacement, thereby reducing repair time and cost.

[0018] In the present invention, the lithium battery steel shell can protect the lithium battery body through the provision of a protective component, thereby increasing the mechanical strength of the lithium battery, improving its anti-extrusion, anti-bending and anti-vibration capabilities, and reducing the damage of the battery caused by excessive force during use;

[0019] The utility model provides auxiliary components, so when the battery needs to be repaired or replaced, there is no need to dismantle the entire shell. It is only necessary to easily remove the lithium battery body to perform necessary maintenance or replacement, thereby reducing repair time and cost. BRIEF DESCRIPTION OF THE DRAWINGS
