Cell assembly
Cell assembly is a crucial step in the battery production process, which directly affects the performance, safety and life of the battery. Cell assembly usually includes winding process, lamination process, packaging and liquid injection, and preliminary sealing and so on. Reasonable control of each step ensures high efficiency and long-term stability of the battery.
Cell assembly
The cell assembly process includes winding and lamination technology, which forms the core structure of the battery by different ways. Packaging and injection ensure sufficient electrolyte and protect the battery interior to prevent leakage; The initial seal provides the basis for the final package. Every step is critical to ensure the best possible battery performance, stability and safety.
Specific information
The winding process is to alternately wind the positive electrode, the negative electrode material and the diaphragm together to form a reel-like cell. Through this process, the capacity and energy density of the battery are effectively improved. The winding process is suitable for cylindrical batteries and soft pack batteries.
The winding process makes the cell have high energy density and structural stability by closely combining the electrode and the diaphragm, and improves the charge and discharge performance of the battery.
The lamination process is suitable for square batteries, where the positive electrode, negative electrode and diaphragm are stacked layer by layer to form a layered structure. The electrodes and diaphragms of each layer are strictly aligned to ensure the consistency and uniformity of the battery.
The lamination process can ensure the uniform distribution of materials inside the battery and stable structure, improve the capacity and electrochemical performance of the battery, suitable for large capacity and high energy density batteries.
Packaging process is to complete the winding or lamination of the cell into the shell to ensure that it is not affected by the external environment during use. After packaging, the electrolyte is injected to ensure that the electrochemical reaction in the battery can be carried out smoothly.
The packaging process improves the mechanical strength and safety of the battery, prevents the leakage of the electrolyte, and ensures the normal operation of the battery through the injection of liquid, providing the necessary conductive medium for charge and discharge.
Preliminary sealing is the initial sealing of the battery cell after packaging, usually by welding, bonding and other ways. The purpose of this step is to ensure that the inside of the battery is not contaminated, to prevent electrolyte leakage, and to lay the foundation for an eventual tight seal. The initial seal ensures the sealing of the electrolyte inside the cell, avoids leakage, and provides protection for the subsequent final seal, enhancing the safety and stability of the battery.
