Aluminum Shell For Samsung Li Ion Battery Aluminum Shell
Products Description
The Aluminum shell for samsung li ion battery Aluminum shell is a precision-engineered metal component specifically designed to house and protect standard cylindrical lithium-ion cells manufactured by Samsung (such as the 18, 21, and 26 series). Far more than just a physical enclosure for the battery pack, it serves as a multifunctional system component that integrates mechanical protection, thermal management, electrical insulation, and structural support. Acting as the critical structural interface connecting individual cells to the larger battery module or pack, it exerts a decisive influence on the safety, reliability, and energy density of the entire battery system.
Product Properties and Characteristics
Electrical Properties
Rechargeable Aluminum Shell exhibits excellent electrical conductivity, serving as a reliable grounding terminal for battery cells to mitigate static accumulation and reduce the risk of short circuits. An optional surface insulating coating is available to meet inter-module insulation requirements, offering high insulation resistance and eliminating potential leakage hazards.
Physical Characteristics
Lightweight and low-density for EV Car Battery Shell-approximately 50% lighter than steel casings. It features high structural strength with a tensile strength exceeding 140 MPa, offering robust resistance to impact and vibration. The product boasts high dimensional precision with tight tolerances, as well as a smooth, flat surface free from burrs or deformation.
Chemical Characteristics
Chemically stable; the anodized surface film provides excellent resistance to corrosion, electrolytes, sulfurization, and moisture. Composed of eco-friendly, cadmium-free, and lead-free materials, Lithium-ion Battery Aluminum Shell complies with international environmental standards and ensures that no harmful substances are released.
Detailed Features
A compliant explosion-proof line must exhibit uniform depth and precise positioning, ensuring that Power Battery Shell fractures along the predetermined path under the specified pressure.
The oxide film on the Lithium Batteries Square Aluminum Shell inner wall must be continuous, dense, and free of pinholes-a condition verified through high-pressure testing.
The fillet radius (R-angle) region transitioning from the base to the sidewalls of the Prismatic Cell Aluminum Battery Case must be smooth and free of wrinkles, with the rate of wall thickness reduction remaining within safe limits.
Manufacturing Process Advantages
Precision Stamping
High-speed stamping presses paired with precision dies are utilized to form the cylindrical body in a single operation, thereby minimizing the number of weld seams. The dies boast a service life of 500,000 to 1 million cycles, making this process ideal for mass Power Battery Cover Plate production.
Laser Welding
Fiber lasers are employed to weld the cylindrical body to the bottom cap. The weld seam width is precisely controlled within the range of 0.3–0.5 mm, resulting in a minimal heat-affected zone and low welding deformation. Welding speeds for Rechargeable Aluminum Shell can reach 30–60 mm/s.
Spin Forming
For bottom structures requiring a rounded transition, a spin-forming process is applied to achieve a smooth, seamless transition, thereby preventing the EV Car Battery Shell's potential cracking that can sometimes occur during stamping.
