Titanium Anodes for Electrolytic Copper Foil Production
Engineered for ultra-thin copper foil production, stable electrodeposition, and high-current-density electrochemical cells. Hele Titanium provides MMO coated titanium anodes, custom electrolytic cell electrodes, and engineered current distribution assemblies for battery foil, PCB foil, and electronic materials manufacturing.
Ultra-Thin Copper Foil Requires Stable Electrodeposition
Electrolytic copper foil production uses controlled electrodeposition to form ultra-thin copper foil from copper sulfate electrolyte onto a rotating cathode drum.
Current density, electrolyte composition, copper concentration, acid level, additives, temperature, drum condition, and anode coating stability directly affect foil thickness uniformity, surface quality, tensile performance, energy consumption, and production consistency. Hele Titanium supports these systems with MMO coated titanium anodes, custom electrolytic cell electrodes, and engineered current distribution assemblies.
For copper foil production projects, anode selection should be based on foil application, target thickness, current density, electrolyte chemistry, cell geometry, drum size, coating requirement, and documentation needs.
Working Principle
In copper foil electrodeposition, copper ions are reduced onto a rotating cathode drum to form a continuous copper foil layer. The titanium anode supports the required anodic reaction while maintaining stable current distribution and compatibility with the electrolyte.
Typical Electrolytic Copper Foil Production System
A copper foil production system combines copper sulfate electrolyte circulation, MMO titanium anodes, a rotating cathode drum, DC power supply, filtration, foil peeling, and winding control to produce continuous ultra-thin copper foil.
Engineering Note
Final anode configuration depends on foil thickness target, drum size, current density, electrolyte composition, additive system, cell geometry, and expected service life.
