What are the precautions when designing lithium battery casing?

What should be paid attention to when designing lithium battery casing? 1. Pole piece connection: It is recommended to use ultrasonic or spot welding welding method. The design of the lithium battery shell should make the pole piece free from external force. 2. The soldering time cannot exceed 3 seconds, and the number of times cannot exceed 5 times. The next soldering can only be performed after the pole pieces are cooled. 3. It is strictly forbidden to directly heat the battery cell, which will be damaged if the temperature is higher than 100℃. 4. Fixation of the lithium battery: the side with the largest area of u200bu200bthe battery should be fixed on the shell, and the battery cannot be loose after installation. 5. Shell toughness: The lithium battery shell should have enough mechanical strength to protect the battery from mechanical impact. 6. The welding temperature of ferrochrome must be controllable and anti-static, and the temperature should not exceed 350°C.
