China Battery Aluminum Foil

The use of china battery aluminum foil with surface treatment of battery conductive substrates is a breakthrough technological innovation. The coated carbon battery aluminum foil foil is to evenly and delicately coat dispersed nano graphite and carbon-coated particles onto aluminum foil. It can provide excellent static conductivity, collect microcurrent of active substances, significantly reduce the contact resistance between positive/negative electrode materials and current collectors, and improve the adhesion between them, reduce the amount of binder used, thereby significantly improving the overall performance of the battery.

Specifications of china battery aluminum foil:

Thickness: 0.008-0.02mm

Width: 400-1350mm

Common alloy states: 1070-H18, 1100-H18, 3003-H18

Application areas: mobile phones or electric vehicle batteries.

The performance and advantages of china battery aluminum foil surface coating:

1. Significantly improve the consistency of battery pack usage and significantly reduce the cost of battery packs. Obviously reduce the increase in dynamic internal resistance of battery cells, improve the consistency of battery pack voltage difference, and extend the life of battery packs.
2. Improve the adhesion of active materials and current collectors, and reduce the manufacturing cost of electrodes. For example, improve the adhesion of positive electrode materials and current collectors using water-based systems, improve the adhesion of nano or submicron positive electrode materials and current collectors, improve the adhesion of lithium titanate or other high-capacity negative electrode materials and current collectors, and improve the qualified rate of electrode manufacturing and reduce the manufacturing cost of electrodes.
3. The adhesion force of the electrode sheet after using coated carbon battery aluminum foil is increased from the original 10gf to 60gf (tested using 3M tape or Scotch-Brite method), and the adhesion force is significantly improved.
4. Reduce polarization, improve rate capability and specific capacity, and enhance battery performance. For example, partially reduce the proportion of adhesive in active materials to improve the specific capacity; improve the electrical contact between active materials and current collectors; reduce polarization and improve power performance.
5. Protect current collectors and extend battery life. For example, prevent corrosion and oxidation of current collectors; improve the surface tension of current collectors and enhance the coating performance of current collectors; replace expensive etched foils or use thinnerbattery aluminumfoils instead of standard thickness battery aluminum foils.
