Electrolytic Copper Foil | Reliable Current Collector
Our battery-grade copper foil is engineered for superior performance in lithium-ion and next-generation batteries. Key advantages include:
-
Ultra-High Purity (≥99.99%): Minimizes impedance for maximum energy efficiency.
-
Precision Thickness Control: Uniform surface (Rz≤1.5μm) ensures consistent electrode coating.
-
Enhanced Adhesion: Micro-roughened surface improves active material bonding.
-
Thermal Stability: Withstands high-temperature calendering processes.
*Ideal for [EV batteries/ESS/consumer electronics] requiring [thinness/durability/cost-efficiency]. Custom widths (200-1500mm) and jumbo rolls available.
