Production process of cylindrical lithium ion battery

The production process of lithium-ion battery is divided into three sections: 1. Electrode production; 2. Cell production; 3. Battery assembly. In the production process of lithium-ion battery, the production of electrode is the foundation, and the production of cell is the core. Battery assembly is related to the quality of lithium-ion battery. The production process of lithium-ion battery includes positive pole pulling, negative pole pulling, positive plate, negative plate, steel shell assembly, liquid injection, detection and packaging.

As we all know, the production process of lithium-ion battery is quite complex. After all, the safety performance of lithium-ion battery products is directly related to the life and health of consumers. In the production and manufacturing of natural lithium-ion battery, there are high requirements for the performance, accuracy, stability and automation level of equipment.

Taking the preparation of electrode slurry in the production process of lithium-ion battery as an example, this link is the most important link in the whole production process. After all, the influence of electrode slurry mixing and dispersion process on product quality is greater than 30%. Why?

The reason is that the preparation of positive and negative paste for lithium-ion battery includes a series of technological processes such as mixing, dissolving and dispersing between liquid and liquid, liquid and solid materials, and changes with temperature, viscosity and environment. In the positive and negative electrode pastes, the dispersion and uniformity of granular active substances directly affect the movement of lithium ion between the two electrodes of the battery, so the dispersion quality of electrode slurry directly affects the product performance of lithium-ion battery.
