Equipment characteristics of the automatic production line of solid-state lithium-ion batteries: This production line is a fully automated production line for round solid-state batteries. The whole process is completed in the glove box, ensuring that the entire process is produced in an oxygen-free and water-free environment, ensuring product quality . In order to ensure the accuracy of the positive electrode material, solid electrolyte, and negative electrode material.
Process characteristics are as follows:
1. Powder injection of cathode material
The key point is the use of a vibrating spiral powder injection method, so that the positive electrode material powder is not passed through the powder injection process, and no residue is attached to the tube wall, ensuring the accuracy of the positive electrode material powder injection.
2. Powder injection of solid electrolyte
It uses high temperature to melt the solid electrolyte first, and then inject the liquid at high temperature, ensuring the accuracy of solid electrolyte powder injection.
3. Powder injection of anode material
It also melts the negative electrode material first, and then performs high temperature injection, which ensures the accuracy of powder injection of the negative electrode material.
