Lithium Battery Aluminum Shell

The primary function of the Lithium battery aluminum shell is to protect the components inside the battery while providing structural support for the entire battery. This aluminum casing is usually made of high-quality aluminum alloy material and has a certain thickness and strength, which can effectively prevent external objects from damaging the inside of the battery.

• Lithium battery aluminum shell can effectively isolate the chemicals inside the battery and prevent electrolyte leakage or battery short circuit, thereby improving battery safety.

• The aluminum shell can help dissipate heat, quickly conduct the heat generated inside the battery, keep the battery working within an appropriate temperature range, and improve the performance and life of the battery.

• The aluminum shell can resist external pressure and impact, protecting the fragile components inside the battery from damage.

Material cutting: We purchase high-quality aluminum alloy sheets from reliable suppliers and then cut them according to the design requirements using high-precision cutting equipment. This ensures that the aluminum shell is the expected size and shape and that the cut surface is flat and free of burrs.

Stamping: The cut aluminum plate is fed into the stamping machine, which is stamped into the required shape and structure according to the design requirements. We use high-precision stamping equipment and technology to ensure each aluminum shell has accurate dimensions and consistent shape.

Cleaning treatment: The stamped aluminum shell needs to be cleaned to remove oil stains and impurities produced during the processing. We use professional cleaning equipment and cleaning agents to ensure that the surface of the aluminum shell is clean and pollution-free.

Inspection and packaging: After strict quality inspection, the aluminum battery casing can be sealed and packaged, ready for shipment.

Stamping and drawing of Lithium battery aluminum shells are critical steps in the manufacturing process:

Stamping: Stamping is the process of placing an aluminum sheet on a punch press and then applying pressure to it using a die to form it into the desired shape. During the stamping process, the aluminum sheet is press-molded into the desired shape, usually a flat, basic shell structure. Stamping can create depressions, holes and edges in aluminum panels according to design requirements.

Stretching: Stretching is a processing process performed on aluminum plates after the stamping process, with the purpose of extending the length of the aluminum plate or changing its shape through stretching. During the stretching process, the aluminum plate is placed on the stretching equipment and a certain amount of tension is applied to make it stretch in a specific direction. This allows the aluminum sheets to form deeper or more complex structures, such as deepening the edges of the shell or forming complex recessed structures.

Through stamping and stretching processes, the aluminum battery square case can be formed into the required structure and shape according to design requirements, thereby providing solid protection and support for the battery components. These processes ensure that the housing has a consistent size and shape, as well as good mechanical properties and surface quality.
