Power Battery Shells
Power battery shells are precision aluminum alloy casings designed for prismatic lithium-ion cells. They primarily serve to encapsulate and mechanically protect the internal components—including electrode sheets, separators, and electrolyte—while providing a stable structural foundation for subsequent processes such as top-cover assembly, hermetic welding, and battery module integration. Tailored for applications involving power batteries for new energy vehicles, energy storage systems, and other high-capacity prismatic cells, we offer manufacturing solutions centered on aluminum alloy stamping, precision deep drawing, forming, trimming, punching, and subsequent precision machining. We provide OEM/ODM development services customized to specific cell dimensions, internal space requirements, top-cover designs, and assembly specifications.

Product Introduction
What is a Power Battery Shell?
The aluminum alloy casing of a prismatic lithium battery is a structural component of the battery cell; its primary function is not merely to "house the cell," but to create an external enclosure with a stable geometric structure.
Typical structural elements include:
Battery Aluminum Shell - Prismatic aluminum alloy battery casing
Bottom Structure - Integrally formed bottom
Side Walls - Surrounding sidewalls
Opening / Sealing Edge - Casing opening and sealing rim
Positioning Features - Positioning, assembly, and auxiliary structures
Reinforcement Areas - Areas of localized structural reinforcement
An integrally formed structure minimizes unnecessary casing joints and establishes a continuous sealing boundary for the subsequent assembly of the top cover. Research and patented technologies regarding the manufacture of such prismatic battery casings largely focus on deep drawing, DI (Drawn and Ironed) forming, and laser welding of the casing to the cover plate.
Aluminum shell for lithium ion prismatic cell advantages
Environmental protection and energy saving
Aluminum alloy is a recyclable material. Our product design fully considers environmental protection factors, which not only reduces the impact on the environment during the production process, but also promotes the recycling of resources.
Flexible and diverse design
Power Battery Shells are easy to process and can be customized in different shapes, sizes, and surface treatment effects according to customer needs to meet diverse design needs and enhance the market competitiveness of products.
High energy efficiency ratio
The optimized structural design reduces the internal resistance of the battery and improves the energy conversion efficiency, so that each battery can output electricity with higher efficiency and extend the use time of the equipment.
Excellent safety performance
Through rigorous testing and certification, our Lithium Battery Aluminum Case has excellent explosion-proof and short-circuit-proof capabilities, ensuring safe and stable operation under various extreme conditions to protect user safety.
Economic cost-effectiveness
Although the initial investment may be slightly higher, due to its excellent durability, long life, and low maintenance cost, choosing our products is more cost-effective in the long run.
Easy to integrate and maintain
The standardized design makes the battery module easy to install, disassemble, and replace, which facilitates system integration and maintenance and reduces the difficulty of use and operation and maintenance costs for users.
Packaging and Shipping for Power Battery Shell
Regarding transportation methods, we can provide sea, land, and air transportation. No matter what transportation method the customer requires, we will try our best to meet it. In short, in order to ensure the safety of Power Battery Shells during transportation, we will choose the most appropriate packaging and transportation methods and strictly abide by relevant regulations and standards.
1. Individual packaging: Each Aluminum Prismatic Casing should be individually packaged in a completely closed inner packaging, such as blister packaging or cardboard, to ensure that the battery is fully protected.
2. Anti-short-circuit measures: During the packaging process, the product should be completely covered to avoid short circuits or contact with any conductive materials. The packaging material should have good insulation and buffering properties to effectively protect the battery from external impact.
3. Compliance with standards: The packaging material needs to be verified to meet the test requirements of the UN test manual. This ensures that the packaging can withstand certain pressure and impact during transportation, while preventing battery leakage, fire, or explosion.
