Proses Pembuatan Baterai Ion Lithium Tipe Silinder 18650

Summary

The video script outlines the intricate process of manufacturing lithium-ion batteries at the PT University Center of Excellence for Electrical Energy Storage Technology. It begins with the mixing of cathode and anode materials, followed by coating, rolling, and cutting to precise sizes. The electrodes are then spot-welded and laminated to prevent short circuits. The anode and cathode are rolled into a jelly roll form, checked for shorts, and assembled into a cylinder. The cell is filled with electrolyte, sealed, and tested for performance and internal resistance. This comprehensive overview showcases the meticulous steps involved in creating efficient and reliable lithium-ion batteries.
