Conductive Carbon Coated

1. The inhibition of cell polarization, reduce the heating effect and improve the rate performance;

2. Reduce the battery internal resistance, and decrease the circulation process of dynamic resistance increase;

3. Improve the consistency, increase the battery cycle life;

4. Improve the adhesion of and active materials, reduce the pole piece manufacturing cost;

5. Protect collection of fluid from the electrolyte corrosion;

6. Improve lithium iron phosphate, lithium titanate materials processing performance.

Conductive coating:

Using functional coatings for surface treatment of battery conductive substrate is a breakthrough of technical innovation, coated carbon foil/copper foil is to spread good nano conductive graphite and carbon-coated particles, fine and uniform coating on aluminum foil/copper foil. Static electrical conductivity can provide an excellent collection of active material micro electric current, which can greatly reduce the positive/negative material and collector, the contact resistance between the and can improve the adhesive ability between the two, can reduce the use amount of binder, which creates a significantly improve the overall performance of the battery. Can be divided into water-based coating (water system) and oil (organic solvent system) two types
