Li Ion Pouch Cell Aluminum Shell

Li ion pouch cell Aluminum shell has a tight structural design to prevent electrolyte leakage and the impact of the external environment on the battery core. The use of aluminum battery shells can ensure safe isolation and thermal management between battery cells, providing safety guarantee for the battery system of electric vehicles. 

• Thermal Management: Li ion pouch cell Aluminum shell has good thermal conductivity, which helps evenly distribute and dissipate heat inside the battery pack. Helps maintain the temperature stability of the battery pack and extend battery life.

• Safety: The battery pack is easily affected by collision, vibration, pressure, etc. The aluminum casing usually has high strength and pressure resistance, which can effectively protect the battery cells from external damage.

• Manufacturing process: The battery packs are usually manufactured using a deep drawing process. These processes ensure the dimensional accuracy and surface quality of the housing while improving production efficiency.

Continuous stamping is a commonly used metal processing process suitable for mass production of Li ion pouch cell Aluminum shells.

1. Preparation: Aluminum plates need to be prepared as raw materials for processing.

2. Cutting: The aluminum plate is further cut into sheets to facilitate subsequent processing.

3. Continuous stamping: A continuous stamping machine is used to continuously stamp aluminum sheets.

4. Trimming: During the continuous stamping process, the excess aluminum material of the finished aluminum battery case is cut off.

5. Finished product processing: The processed aluminum battery case parts need to undergo subsequent processing, including deburring, cleaning, drying and other processes to ensure that meets the design requirements.

6. Quality inspection: further inspect the processed aluminum battery case.

7. Packaging and storage: Pack the qualified aluminum battery case parts, mark them, and store them in a designated area for subsequent assembly.

• Good heat dissipation effect: Excellent thermal conductivity not only helps to maintain a uniform distribution of the internal temperature of the battery pack, improves the working efficiency and stability of the battery, but also improves the heat dissipation efficiency of the battery pack, prolongs the life of the battery, and provides a good solution for electric vehicles. Reliability and continued performance provide important guarantees.

• Effectively resist impacts: When driving a car, you may encounter bumps, collisions or other external impacts, and the aluminum battery case can withstand a certain degree of impact and disperse it to the surrounding environment, thereby protecting the battery cells inside. or the battery pack is protected from damage.

• Stable performance: Li ion pouch cell Aluminum shell can also maintain stable performance under harsh environmental conditions. For example, in high temperature or humid environments, aluminum battery cases are not susceptible to corrosion or oxidation and can maintain good appearance and performance, thereby extending the life of the battery case.

High material utilization: Continuous stamping technology can effectively utilize raw materials and minimize waste. By rationally designing molds, efficient use of materials can be achieved and the generation of waste can be reduced.

High precision: Due to the high precision of continuous stamping machinery and equipment, the size and shape of parts during the stamping process can be precisely controlled, thus ensuring a high degree of accuracy and consistency of processed parts.

Wide applicability: Continuous stamping technology is suitable for various metal materials, as well as parts of various shapes and sizes. Therefore, it has a wide range of application fields, including automobile manufacturing, electronic products, home appliances, etc.
