Carbon-coated aluminum foil role：
Inhibit battery polarization, reduce thermal effects and improve the rate performance;
Reduce the battery internal resistance, and significantly reduce the cycle of dynamic resistance increase;
Improve consistency, increase battery cycle life;
Improve the adhesion of the active material and the current collector, and reduce the manufacturing cost of the pole piece;
The protective collector fluid is not corroded by the electrolyte;
Improve lithium iron phosphate battery high and low temperature performance, improve lithium iron phosphate, lithium titanate material processing performance.
