1.The function of adhesivesCathode and anode slurries：
Provide viscosity to ensure that particles in the slurry do not easily settle and maintain sslurry stability
Provide viscosity for good fluidity
Provide viscosity to facilitate effective dispersion of materials
Cathode and anode electrodes：
Provide adhesive force to ensure good contact between active materials, conductive carbon, and current collectors.
Provide adhesive force to ensure good contact between particles.
The rolling process is resistant to deformation and breakage.

4.Usage SuggestionsWith numerous manufacturers and a wide range of adhesive models available,how do we make the right choice?
4.1.Choose mainstream manufacturers' products to ensure quality
4.2.Opt for products that have been used in commercial batches for reliable performance
4.3.Clarify the application requirements of the product and make targeted selections of
adhesives based on the characteristics of the research materials
Recommended that everyone clearly consider the product requirements and material characteristics before use.
If you have any questions or need advice, please feel free to consult with Canrd Technology.

Problem of PVDF Glue Solution
6.
DiscolorationIn practical use, PVDF glue solutions often encounter the issue of darkening in color, sometimes even turning a dark red hue. What is the reason for this? Is it still usable?
