Research Progress on Microstructure Regulation of Pure Titanium for Cathode Roll of Electrolytic Copper Foil

With the upgrading of electronic communications and the development of new energy vehicles, printed circuit boards and lithium-ion batteries have put forward more stringent requirements for the comprehensive performance of electrolytic copper foil. The cathode roller is the key equipment for the production of electrolytic copper foil. The crystal structure on the surface of the cathode roller titanium cylinder plays a decisive role in the nucleation and growth of electrolytic copper foil. Around the key problem of pure titanium microstructure regulation for electrolytic copper foil, the casting process,thermal processing process, rare earth microalloying and properties were summarized, the microstructure genetic relationship between titanium cathode and electrolytic copper foil was prospected, in order to provide references for the design of titanium materials and electrolytic copper foil with excellent microstructure properties.
