- •
Effects of annealing to a Laves phase-related BCC metal hydride alloy are reported.
- •
900 °C for 12 h is found to be optimal for electrochemical properties.
- •
Annealing at 1000 °C promotes formation of Ti2Ni phase.
- •
Annealing at 1100 °C, a 蟽-VNi phase is formed.
- •
The open-circuit voltage decreases with the increase in plateau pressure.
