Substitution of Ti-Cu-layered composite materials for single-titanium substrates in traditional titanium electrodes was proposed, and the different performances between the novel electrode and the traditional Ti coated electrodes were investigated. The potential distribution over the electrode surface and linear scanning voltammetry curves were analyzed. The results show that the Ti-Cu-based coated electrode possesses higher conductivity due to its new substrate material, which is conducive to both potential distribution and current distribution over the electrode surface. The Ti-Cu-based coated electrode has better electrocatalytic activity, as well as excellent reaction stability under high-current density. When used in electrolysis industry, the novel electrode can reduce the electrolysis voltage and increase current density, thus enhancing the current efficiency and the productivity.：Substitution of Ti-Cu-layered composite materials for single-titanium substrates in traditional titanium electrodes was proposed, and the different performances between the novel electrode and the traditional Ti coated electrodes were investigated.
