Formation and separation Formation and volume separation are important steps in the battery production process, which are mainly used to improve the performance and stability of the battery and ensure the balance of the battery pack. This process usually occurs after the battery assembly is completed, after the initial sealing, injection and other processes, the purpose is to activate the…
Preliminary seal The initial seal is a very critical step in the battery assembly process, mainly the first seal of the battery to ensure that the electrolyte inside the battery does not leak, while preparing for the subsequent final seal. Initial sealing usually occurs after the packaging and injection process, in order to prevent the electrolyte volatilization, external pollution and…
Encapsulation and injection Packaging and injection is an important part of battery production, usually after the cell assembly, in order to provide protection for the battery, ensure its normal operation, and prevent electrolyte leakage. This process involves loading the cell into the housing and injecting the electrolyte, ensuring that the electrochemical reaction of the battery can proceed smoothly. Encapsulation and…
Lamination process Lamination process is an important process in battery manufacturing, which is mainly used in the production of square batteries. It forms the core structure of the battery by stacking the positive plate, negative plate and diaphragm layer upon layer. This process can ensure the precise alignment and uniform distribution of the various components inside the battery, which is…
Winding technology The winding process is one of the core steps in battery manufacturing, especially suitable for the production of cylindrical and flexible batteries. The process forms the core structure of the battery by alternately winding the electrode material and the diaphragm into a tight drum shape. The winding process has a direct impact on the energy density, power density,…
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.

Roll and slice Rolling and slicing is an important step in the battery electrode manufacturing process, which is mainly used to adjust the thickness, density and shape of the electrode to ensure the performance of the electrode and the consistency of production. Rolling adjusts the thickness and density of the electrodes by mechanical pressure, and slicing cuts the rolled electrodes…
Battery coating and drying Coating and drying are crucial steps in the manufacturing process of battery electrodes, which determine the uniformity of electrode materials, performance and long-term stability of the battery. Coating is to evenly coat the slurry to the surface of the collector (such as aluminum foil or copper foil), drying is to remove the solvent, so that the…
Critical control point Critical control points are very important in the process of battery slurry preparation, which involves precise monitoring and adjustment of many links. The optimization of each control point is directly related to slurry quality, electrode performance, and final battery performance. Critical control point The key control points in the preparation of battery slurry are viscosity, mixing time…
Raw material mixing Raw material mixing is a key step in the process of battery slurry preparation, which directly affects the uniformity and stability of slurry and the final performance of battery. In this link, it is mainly to fully mix all kinds of raw materials (active materials, conductive agents, adhesives and solvents) of the battery to ensure the uniform…
