Effects of Ti substitution for Zr on the electrochemical characteristics and structure of AB2-type Laves-phase alloys as metal hydride anodes

•TixZr1−xLa0.03Ni1.2Mn0.7V0.12Fe0.12 (x = 0.12, 0.15, 0.18 and 0.22) alloys were studied as metal hydride battery anodes.•Annealed Zr/Ti-based AB2 alloys crystallize with an FCC C15 Laves phase structure.•The maximum discharge capacity of the alloys as anode electrode of the MH battery reaches 466 m...
