In the lithium-ion battery cell assembly process, there are two main technologies: winding and stacking. These two technologies set up are always related to the below key technical points: Battery cell space utilization, battery cell cycle life, cell manufacturing efficiency and manufacturing investment. Overview 1. What is Winding Technology? 2.
1.Introduction to Winding Process The winding process is a critical component in the manufacturing of lithium batteries. 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.
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.
When comparing winding vs stacking battery, the stacking process can give better play to the advantages of large electric cores, which is superior to winding in terms of safety, energy density and process control. In the future, the energy storage batteries will be mainly square stacking batteries.
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.
Prismatic cell: Both stacking and winding processes can be used. At present, the main technology direction in China is mainly winding and is transiting to stacking.
