The diagram illustrates the lithium battery production process

The production of lithium batteries requires many complicated processes. The following diagrams illustrate each process in the lithium battery production process. The first step is negative electrode homogenization, the second step is positive electrode homogenization, the third step is coating, and the fourth step is rolling. The fifth step is slitting, the sixth step is baking, the seventh step is winding, the eighth step is into the shell, the ninth step is spot welding, the tenth step is baking, the eleventh step is liquid injection, the twelfth step is welding the cap, the thirteenth step is cleaning, the fourteenth Step 15: Dry and store; Step 15: Detect alignment; Step 16: Print the shell; Step 17: Form an assembled battery, which is given a certain current to excite the positive and negative active materials of the battery. Finally, the battery has the ability to discharge. The electrochemical process is called chemical conversion, and the battery can only be used as a power source after chemical conversion. The eighteenth step of OCV measurement The nineteenth step of storage at constant temperature The 20th step of capacity division During the manufacturing process, the actual capacity of the battery cannot be completely consistent due to technological reasons. After a certain charge and discharge test, the batteries are classified by capacity The process is called sub-capacity.
