  Lithium ion batteries as positive electrode materials: advantages of carbon coated aluminum foil in lithium battery applications

  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 during the cycling process;

  3. Improve consistency and increase battery cycle life;

  4. Improve the adhesion between the active substance and the collector, and reduce the manufacturing cost of the electrode;

  5. Protect the fluid collector from corrosion by the electrolyte;

  6. Improve the processing performance of Lithium iron phosphate and Lithium titanate materials.

  The use of functional coatings for surface treatment of battery conductive substrates is a groundbreaking technological innovation. Carbon coated aluminum foil/copper foil refers to the uniform and delicate coating of dispersed nano conductive graphite and carbon coated particles on the aluminum foil/copper foil. It can provide excellent static conductivity, collect micro currents of active substances, significantly reduce the contact resistance between positive/negative electrode materials and current collectors, and improve the adhesion ability between the two. It can reduce the use of adhesives, thereby significantly improving the overall performance of the battery.
