How to improve the conductivity of conductive carbon black in lithium-ion batteries?

Optimize the dispersion of carbon black: through the use of appropriate dispersants, improve the dispersion process, etc., to ensure that conductive carbon black in the electrode slurry uniform dispersion, reduce agglomeration, increase the effective contact area with the active material.

Surface treatment: Appropriate surface modification treatment of conductive carbon black, such as chemical modification, to improve its compatibility and binding force with the electrode material, and then improve the conductivity.

Composite use: The composite use of conductive carbon black with other conductive materials such as carbon nanotubes, graphene, etc., using the advantages of different materials to collaboratively improve electrical conductivity.

Adjust the amount of addition: precisely control the amount of conductive carbon black added to find an optimal ratio that ensures good electrical conductivity without having too much negative impact on other properties.

Optimization of electrode structure design: Reasonable design of electrode microstructure to build a more favorable conductive network channel for conductive carbon black.

Improve the battery manufacturing process: for example, optimize the coating, drying and other links to ensure that conductive carbon black can give full play to its conductive role.
