【Abstract】 The influence of alloy powder particle size and working temperature on the electrochemical characteristics of Ti_ 0.17Zr_ 0.08V_ 0.35Ni_ 0.10Ni_ 0.30 electrode were investigated. The results show that the discharge capacity increases, but the cyclic stability worsens with the decrease of the alloy powder particle size. The content of carbonyl nickel powder used as conduct agent almost does not affect the maximum discharge capacity of this alloy electrode. With the increasing of the working temperature, the cyclic stability, the charge voltage, the discharge voltage decrease. The solubility of vanadium in the KOH electrolyte strongly depends on the working temperature.更多还原
