Function Of Carbon Coated Aluminum Foil For Lithium-ion Batteries

Feb 18,2022.

Carbon coated aluminum foil is made of conductive carbon-based composite slurry and high-purity electronic aluminum foil by transfer coating process.surface treatment of battery conductive substrates with functional coatings is a breakthrough technological innovation.carbon-coated aluminum foil/copper foil is to uniformly and delicately coat the dispersed nano-conductive graphite and carbon-coated particles on the aluminum foil/copper foil.

Carbon-coated aluminum foil for lithium-ion batteries can provide excellent static conductivity and collect the microcurrent of active materials, which can greatly reduce the contact resistance between the positive and negative electrode materials and the current collector, and can improve the adhesion between the two,the amount of binder used can be reduced, resulting in a significant improvement in the overall performance of the battery.

The performance effect of carbon-coated aluminum foil on capacitors is roughly divided into six types;

1. Suppress battery polarization, reduce thermal effects, and improve rate performance;

2. Reduce the internal resistance of the battery, and significantly reduce the dynamic internal resistance increase in the cycle process;

3. Improve consistency and increase battery cycle life;

4. Improve the adhesion between the active material and the current collector, and reduce the manufacturing cost of the pole piece;

5. Protect the current collector from being corroded by the electrolyte;

6. Improve the high and low temperature performance of lithium iron phosphate batteries, and improve the processing performance of lithium iron phosphate (LiFePO4)and lithium titanate materials.
