Aluminum Shell For Single Cell Lithium Ion Battery
Products Description
In the current trend of new energy systems developing towards higher energy density and safety standards, the aluminum shell for single cell lithium ion battery is no longer merely a "container," but a key module involved in overall performance construction. This product is developed for single-cell prismatic lithium-ion batteries, using high-performance aluminum alloy materials. Through precision forming and multi-process manufacturing, it achieves a highly efficient balance between structural strength, sealing performance, and lightweight design.
This aluminum casing not only provides cell protection but also exhibits excellent performance in thermal conductivity, impact resistance, and corrosion resistance, making it suitable for engineering applications with extremely high reliability requirements.
Materials Science: Performance Support from Premium Aluminum Alloys
High-purity 3003/1100 series aluminum alloys
For the complex operating environments of batteries, we select aluminum-manganese alloys with excellent machinability and corrosion resistance. Their lightweight properties effectively improve the module's energy density.
Superior thermal conductivity
The naturally high thermal conductivity of aluminum alloys helps the battery dissipate heat rapidly during charging and discharging, significantly reducing the risk of thermal runaway.
Excellent ductility and explosion-proof performance
Under extreme pressure, carefully selected materials provide the necessary buffer space, combined with an explosion-proof valve design, ensuring safe pressure relief of the system.
Manufacturing Advantages and Production Processes: Industrial Implementation of Micron-Level Precision
| Multi-Station Progressive Die Deep Drawing Process | Abandoning traditional single-stage stamping, we employ high-speed progressive die linkage technology. During the drawing process, by precisely controlling the dynamic curve of the blank holder force and drawing speed, combined with micro-spraying of special drawing oil, we eliminate the severe unevenness in wall thickness caused by drawing (thicker at the opening, thinner at the bottom), ensuring the consistency of each cross-section. |
| Stress Relief and Nanoscale Cleaning | The stamped Aluminum Case for the primary lithium iron battery LiFeS2 carries residual internal stress, which we release through a specific heat treatment process to prevent deformation during subsequent processing. It then undergoes multi-stage ultrasonic and plasma cleaning processes in a cleanroom to thoroughly remove surface brushing oil and microscopic metal debris, ensuring the shell's internal cavity meets battery-grade "absolute cleanliness" (metal foreign matter control reaches PPB level). |
| Precision surface treatment and passivation | We offer original color passivation or special conductive oxidation treatments to meet the welding process requirements of different customers. This not only improves the salt spray corrosion resistance of the housing (meeting the requirements of harsh marine or high humidity environments) but also precisely controls the laser reflectivity of the housing surface, eliminating pain points such as poor welding and porosity. |
