What are the advantages of carbon coated aluminum foil and copper foil?
3, reduce polarization, increase magnification and gram capacity, and improve battery performance. Such as:Partially reduce the ratio of the adhesive in the active material and increase the capacity;? improve electrical contact between the active material and the collector;Reduce polarization and improve power performance.4. protect the collector and prolong the service life of the battery. Such as:? prevent extreme corrosion and oxidation;Increasing surface tension of collector surface and enhancing the easy coating performance of collector;Alternative high cost etch foils or substitute thinner foil for standard foil.
2, increase the adhesive force of the active material and the collector, and reduce the manufacturing cost of the electrode. Such as:? improve adhesion of cathode materials and collector for use in aqueous systems;? improve adhesion of nanoscale or sub micron cathode materials and collectors;? improve adhesion of lithium titanate or other high capacity negative electrode materials and collectors;Increasing the pass rate of the wafer and reducing the manufacturing cost of the pole piece.The use of carbon coated aluminum sheet after adhesion from 10GF increased to 60gf (with 3M tape or 100 lattice Daofa), the adhesion force increased significantly.
Performance advantages of coated carbon foil / copper foil1, significantly improve the consistency of battery usage, greatly reduce battery costs. Such as:Significantly reduce the dynamic resistance of the core;Increase battery pressure consistency;Extend battery life;? substantially reduce battery costs.
