Products Description
What is lithium battery electrode piece making/production?
Lithium battery production process – production process: Lithium battery electrode piece production is to automatically welding the electrode tabs according to the required parameters after the electrode pieces are cutting by the slitting machine/cutting machine.
Completion process:
- Install the electrode lug material and high-temperature tape, adjust the equipment parameters of the corresponding model, then install the cut pole roll, and enter the film machine through traction;
- Ultrasonic Spot Welding System:
- Spot welding tabs that meet process parameters;
- Precisely weld in the gap between the pole pieces and the foil;
- The positive tab is welded in the middle of the electrode piece required for battery winding;
- The negative electrode tabs are welded to both sides of the electrode pieces required for battery winding.
- High temperature tape for electrode tabs:To achieve the insulation effect and prevent short circuit of the electrode pieces, collect the electrode pieces with welded tabs into electrode piece rolls;
- Battery electrode making process completed.
The electrode making machine corresponds to the solution for the winding process of cylindrical batteries/pouch cell batteries, and corresponds to another equipment (die cutting + stacking machine). The stacking process makes electrodes.
Xiaowei can provide fully automatic film making machines for pilot battery production lines, as well as fully automatic film making machines with integrated winding functions.
