2: Processing Flow:

3: Technical specifications: 

• Pre-stretching rate: 2~5‰.

• Inlet stretching tension reduction: 15~30%.

• Outlet elongation rate: 7~9‰.

• Outlet stretching tension reduction: 15~30%.

• Elongation rate measurement mechanism.

• Closed-loop control of tab heating temperature.

4: Technical Features:

Equipped with a pre-stretching mechanism to pre-stretch the two electrode tabs by 2-5‰, reducing the tension on the two electrode tabs at the inlet stretching section, and lowering the original tension by approximately 15-30%.

Equipped with a tab heating treatment mechanism at the outlet stretching section, reducing the tension required to stretch the electrode by 7-9‰, lowering it by approximately 15-30%.

The heating temperature is closed-loop controlled with the electrode elongation rate. An elongation rate measurement mechanism is added to adjust the temperature of the tab heating mechanism based on real-time changes in the elongation rate.

5: Application:

 Positive electrode production process for battery electrodes.
