摘要：

In this paper, Magneli phase Ti4O7 powders were successfully synthesized and used to fabricate high quality Ti4O7 electrodes by the spark plasma sintering (SPS) technique. The micro-structure, conductivity and electrochemical properties of the Ti4O7 electrode were investigated respectively. Furthermore, temperature's effect on the electrochemical properties of Ti4O7 working electrode was studied by the cyclic voltammetry measurements under strong sulfuric acid and alkaline conditions at different temperature to simulate actual operating temperature in various electrolyte such as in lead-acid or zinc-air batteries. The results showed that Ti4O7 electrodes prepared by SPS without doping of adhesives had high conductivity, favorable electrochemical activities in function of temperature and electrochemical stability under strong sulfuric acid and alkaline conditions. It would be feasible candidate to bipolar lead-acid battery and used as air cathodes in zinc-air batteries.
