🔋 Lithium-Ion Battery Production Process
This paragraph outlines the process of making lithium-ion batteries, a key technology in electrical energy storage. It starts with the mixing of materials for the cathode and anode, which takes 12 hours to ensure homogeneity. The mixed materials are then layered onto the surface of rubber collector electrodes using a coating machine. The electrodes are compacted using a rolling press machine to ensure the materials adhere tightly. The electrodes are cut to size using a cutting machine. The next step involves spot welding to attach aluminum tabs to the cathode and nickel tabs to the anode. This is followed by a short circuit test to ensure safety and proper functioning of the battery.
🔧 Post-Production Battery Assembly and Testing
After the electrodes are prepared, the anode and cathode are rolled together using a semi-automatic winding machine to form a jelly roll, which is a compacted version of the battery. To prevent short circuits, a secondary check is performed. The jelly roll is then placed on a cylinder gauge for further measurement and installation. An electrolyte test is conducted within a casing. The cover of the cylinder cell is sealed, and the battery undergoes a grading process on an analyzer machine to check its performance. The internal resistance of the battery is also tested to ensure it meets the required standards before the battery is considered complete.
🛠️ Final Battery Inspection and Quality Control
The final paragraph discusses the inspection and quality control processes of lithium-ion battery production at the SPUI unit. It highlights the importance of checking the internal resistance of the batteries using a specialized tester. This step is crucial to ensure that each battery meets the quality and performance standards before it is released for use. The video concludes with a brief overview of the entire battery-making process, emphasizing the precision and attention to detail required at each stage.
