Abstract

Abstract

A new vanadium based negative electrode alloy V65Ti20Ni15 for automotive batteries was prepared by self propagating high temperature synthesis (SHS) with different contents of Al or Cr. The microstructure, electrochemical cycle stability and corrosion resistance of the alloy were tested and analyzed. The results show that Al or Cr is helpful to improve the internal structure, electrochemical cycle stability and corrosion resistance of the alloy. The best electrochemical cycle stability and corrosion resistance can be obtained for V59Ti20Ni15Al3Cr3 alloy with Cr and Al added. Compared with the V65Ti20Ni15 alloy without alloying elements, the discharge capacity decay rate of V59Ti20Ni15Al3Cr3 alloy with alloying elements Cr and Al is reduced from 85% to 23% after 50 charge-discharge cycles, with the corrosion potential shifted forward by 692 mV. The electrochemical cycle stability and corrosion resistance of the alloy are significantly improved.
