Failure Mechanism Analysis of Titanium Anode for Electrolytic Copper Foils

Electrolytic copper foil stands as a pivotal material in the electronics industry. Anode materials are extensively utilized in the processing of electrolytic copper foils. Given the intricate production conditions of copper foils, there are multifarious factors contributing to the failure of titanium anodes. Presently, there is comprehensive research into the failure mechanisms of titanium anodes under actual complex operational conditions. This paper addresses gaps by juxtaposing failed and new titanium anodes from a copper foil manufacturing facility. It analyzes the macroscopic and microscopic morphological alterations, elemental distribution, and phase composition changes in titanium anodes before and after failure. Additionally, by integrating performance tests such as CV and EIS, the study dissects the failure mechanism of commercially employed titanium anodes.
