Customization process
First, according to the specifications and performance requirements of lithium batteries, the appropriate Power Battery Cover Plates material, such as high-strength aluminum alloy, is selected.
Then, a precision mold is designed and manufactured according to the battery size. The material is shaped into a blank of the cover through a stamping process, which requires accurate dimensions and smooth surface.
Subsequently, the cover is sealed and welded using laser or resistance welding technology to ensure the sealing of the internal environment of the battery. After that, surface treatment, such as anodizing, is performed to enhance its corrosion resistance and aesthetics.
The cover is also subject to strict quality inspection, including dimensional measurement, sealing test and insulation performance test, to ensure that each Power Battery Cover Plate meets high standards.
Finally, the finished product is properly packaged and stored in a dry and clean environment for assembly and use. The entire customization process pays attention to details and quality control to ensure the safety and performance of lithium batteries.

Maintenance Guide
To ensure the long-term stable operation of the Prismatic Lithium Battery Annexe, please follow the maintenance guidelines below:
First, avoid exposing the cover to moisture, high temperature or corrosive environments for a long time to prevent material aging and performance degradation.
01
Check the surface of the Aluminum Cover Plate for Battery regularly. If there are scratches or stains, wipe it with a soft cloth in time and avoid using corrosive detergents.
02
At the same time, check the sealing performance of the cover to ensure that it is not loose or deformed to prevent electrolyte leakage inside the battery.
03
If the cover shows signs of abnormal wear or damage, please replace it immediately to avoid safety hazards.
04
When storing, the Lithium Battery Top Cap should be placed in a dry and cool place, and avoid heavy objects to prevent deformation.
