Abstract
Magneli phase Ti4O7 was successfully synthesized using a TiO2 reduction method, and characterized by X-ray diffraction, scanning electron microscope and BET surface area measurement. Substantial improvements to the cycle life of nickel–zinc cells were obtained by the addition of small amount of Ti4O7 to the negative zinc electrode. The effects of adding Ti4O7 on the electrochemical performance of zinc anode were studied through the anodic polarization curve, constant current charge-discharge and impedance spectra in combination. Ti4O7, as a kind of conductive and porous material, could increase the conductivity of the zinc electrode, and it is able to retain the soluble zincate species in its volume, and suppress the dissolution of ZnO. The cell Ti4O7 added zinc anode reached 320 cycles before its capacity fell below 90% of the initial capacity, while standard cell without Ti4O7 failed after 200 cycles, which tells that Ti4O7 contributes to improve the performance of negative zinc electrode.
