Application of the methods of volumetric electric-spark dispersion for the fabrication Ti-Zr-Ni hydrogen storage alloy

Results of X-ray and electrochemical analyses of properties of the Ti-Zr-Ni powders obtained by the volumetric electric-spark dispersion method in water, alcohol, kerosene, liquid nitrogen and liquid argon are represented. An influence of the working liquids and parameters of discharge pulses on the chemical composition, phase-structural state, electrochemical characteristics and electrical capacity of the obtained powders are considered. The influence of the heat treatment in various liquids on the electrochemical properties of the electrodes fabricated from this powders are investigated. Showed, that the method of volumetric electric-spark dispersion is suitable for fabrication powders of hydrogen storage alloys for nickel/metal hydride batteries
