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.
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.
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.
This process is mainly used in the production of square and cylindrical lithium-ion batteries. Winding machines can be further divided into square winding machines and cylindrical winding machines, which are used for the production of square and cylindrical lithium-ion batteries, respectively.
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.
The manufacturing of lithium-ion batteries is an intricate process involving over 50 distinct steps. While the specific production methods may vary slightly depending on the cell geometry (cylindrical, prismatic, or pouch), the overall manufacturing can be broadly categorized into three main stages:
