To overcome these challenges, alloys featuring body-centered cubic (BCC) structures have emerged as compelling candidates for hydrogen storage, owing to their exceptional capacity to achieve high-density hydrogen storage up to 3.8 wt% at ambient temperatures. Nonetheless, their practical. .
TiFe-based alloys are an ideal choice for the development of stationary energy storage systems due to their reversible hydrogen storage ability at room temperature, high volume hydrogen storage density, low raw material cost, high platform pressure, etc. However, the activation property still needs.
