Lithium battery production process and links

1. Slurry stirring is an important part of lithium-ion battery equipment. The positive electrode slurry of lithium ion battery is composed of binder, conductive agent and cathode material. The negative electrode slurry is composed of binder, graphite carbon powder, etc. The preparation of the slurry includes the mixing, dissolving and dispersing of liquid and liquid, liquid and solid materials; the quality of the slurry dispersion directly affects the quality and performance of the lithium ion battery.

2. Coating determines the consistency and superiority of the battery and occupies a technical position in battery manufacturing. Regardless of the type of battery produced (eg cylindrical or square), the coater used in the manufacture is the same; different types of batteries require different types of winders.

3. In addition to the lithium ion battery winder, there are capacitor winding machines, textile winding machines, and the like. According to the operation mode of the machine, it can be divided into manual winding machine, semi-automatic winding machine and automatic winding machine.

4. The importance of testing projects has become increasingly prominent. Lithium-ion batteries are easily burned or exploded due to short circuit, overcharge, etc. In the application, they will form a finished battery with the protection board. In applications with high energy density, lithium-ion batteries need to be combined in series and parallel to become a lithium-ion battery pack. The battery management system (BMS) is managed.
