It involves the precise and controlled winding of materials such as positive electrodes, negative electrodes, and separators under specific tension, following a predetermined sequence and direction, to form the battery cell. The quality of the winding process directly impacts the performance and lifespan of lithium batteries.
1.Overview of winding equipment classification 1.1 Classification of mainstream winders Lithium battery winding machine is used to wind lithium battery cells, is a battery positive plate, negative plate and diaphragm in a continuous rotation of the assembly into a core package machine.
The battery winding machinehas a positive and negative feeding unit, and the part that winds the positive and negative membranes together is called the winding needle. According to the different shape types of the winding core, the winding equipment can be mainly divided into square winding and cylindrical winding two categories.
During the charge and discharge process of the battery, because the expansion and contraction are inconsistent, the gap between the pole plate and the diaphragm will become larger, when the electrolyte here is not rich, it will affect the play of the capacity, and the long-term use will bring about the safety problem of lithium analysis.
The winding process diagram is shown in the figure. The process involves six motors. Two kinds of synchronization are involved: the synchronization of the unwinding speed of the diaphragm and the speed of the needle; The discharge speed of the pole is synchronized with the speed of the winding needle.
