What is performance advantages of carbon-coated aluminum foil?
4. Protect collector, extend battery life. Such as:
? prevent collector electrode corrosion, oxidation;
? improve current collecting electrode surface tension and enhance the current collecting electrode coating performance and easy;
? higher-cost alternative to replace the original etched foil or foil with standard thinner foil.
3. Reduce the polarization ratio and improve g capacity, improve battery performance.
? As part of the active material to reduce the proportion of the adhesive to improve g capacity;
? improve the electrical contact between the active material and the collector;
? reduce polarization, to improve the power performance.
2. To improve the adhesion of the bonding of the active material and current collector, the material is soft, easy to process and reduce manufacturing costs pole piece. Such as:
? improve the use of water-based systems and adhesion of the positive electrode material collector;
? improve the adhesion of nanometer or submicron cathode material and a collector;
? improve the adhesion or other high-capacity lithium titanate anode material and a collector;
? Increased pole pieces made of qualified rate, lower pole piece manufacturing costs.
1. significantly improve the consistency of the battery pack, significantly reducing the composition of the battery. Such as:
? decreased batteries dynamic resistance increase;
? Increased pressure consistency of the battery pack;
? extend battery life;
? substantially reduce the composition of the battery.
