Good conductive coating is made of dispersed conductive graphite coated particles. It can provide excellent static conductivity and a energy absorbing protection layer. It also provides good covering protective properties. Coating with water-based and solvent, and can be applied in the aluminum, copper, stainless steel, aluminum and titanium bipolar plate.
Now battery positive plate and negative electrode sheet were using a conductive coating.
It has some main advantages.
- protection of collector, and improve battery life cycles, so the energy storage battery can be widely used;
- to improve the active material and the electric pole piece contacts, to improve adhesion;
- increase the specific surface area, to improve the resistance, in particular, high-power battery;
- to improve the battery performance rate.
Conductive coating has a broad future development scenarios, and now many American lithium battery manufacturers are using this technology.
