What are the advantages of carbon-coated aluminum foil in lithium battery applications?
6. improve lithium iron phosphate, lithium titanate materials processing performance.
Double-sided coating thickness: A paragraph 4 ~ 6μm, B section 2 ~ 3μm.
Conductive coating
Using functional coating on a conductive substrate surface-treated cells is a breakthrough technological innovation, carbon-coated aluminum foil / copper foil is to disperse a good conductive graphite and carbon nano-coated tablets, uniform and delicate coated aluminum foil / a copper foil. It can provide excellent static conductivity, micro current collecting the active material, the contact resistance can be largely reduced positive / negative electrode material, and between the collector and can improve the adhesion between the two, the adhesive can be reduced the amount of agent, and thus the overall performance of the battery have a significant improvement. The aqueous coating points (agent system) and oily (organic solvent system) of two types.
3. To improve consistency, increase the cycle life of the battery;
4. improve the adhesion of the active material and current collector, a pole piece reduce manufacturing costs;
5. The collector protection against corrosion electrolyte;
Carbon-coated aluminum foil advantage in the lithium battery applications:
1. inhibiting cell polarization, to reduce thermal effects, improve rate capability;
2. Reduce the battery internal resistance, and significantly reduces the growth cycle of the dynamic resistance;
