AI Customer ServiceIn 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.
Lithium-ion cell products formed by stacking have a higher energy density, a more stable internal structure, a higher level of safety, and a longer life span. From the inside of the cell, the winding corner of the winding process has radians, and the space utilization rate is lower.
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. Cylindrical cell: As a mature product, it always with the winding process. 4. What are the benefits of lithium-ion battery cell that formed by stacking process?
Although the stacking process will expand during the repeated use of the battery, in general, the expansion force of each layer is similar, so the interface can be kept flat. The plates at both ends of the winding are bent, the coating material will be greatly bent and deformed, and powder dropping and burrs will easily occur at the bending place.
The stacking process is to cut the cathode and anode sheets into the required size, then stack the cathode sheets, separator and anode sheets into small cell unit, and then stack the small cell unit to form the final single cell. 3. What technology was used in the lithium-ion battery cell you saw on the market?
From the inside of the cell, the winding corner of the winding process has radians, and the space utilization rate is lower. The stacking process can make full use of the battery space, and the energy density of the cell formed under the same volume of cell design is higher.
