“…The capacity retention of TiV 2.1 Ni 0.3 is only about 60% after 10 cycles. Many studies were performed to improve the poor cycling stability of Ti-V-based alloys, including element doping and substitutions [3][4][5][6][7][8][9], heat treatments [10,11], rapid solidification [12,13] and surface modification [14][15][16]. Other researchers have attempted to explain the reasons behind the degradation.…”

Ti-V Based / High-Rate Dischargeability / Hydrogen StorageThe phase structure and electrochemical properties of TiV 2.1 Ni 0.4 Zr 0.06 Cu 0.03 Cr 0.1 alloys as anode materials for nickel-metal-hydride batteries treated at different temperatures were investigated. The alloys mainly consist of a bcc (V,Ti)H 0.81 main phase and a network structure of hcp C14 laves phase, along the grain boundaries of the main phase. The lattice distortion is induced to a large extent for the sample treated at 1123 K. The electrochemical measurements indicate that the maximum discharge capacity of this sample is decreased, but improved cycling stability and high-rate dischargeability (HRD) are achieved. The deterioration behavior of the HRD for Ti-V-based alloys is discussed in the paper.

“…Considering the somewhat low discharge capacity of AB 5 type alloys [1], usually less than 320 mAh g −1 , some new types of hydrogen storage electrode alloys with higher discharge capacity such as AB 3 type [2,3], V-based [4], Mg-based [5,6] and V-Ti-based [7] alloys were developed.…”
