Light‐Element Vacancy‐Ordered Perovskites A 2 TiH₆ (A = Li, Na, Be, Mg): First‐Principles Design of Advanced Titanium Hydrides for Reversible Hydrogen Storage
Vacancy‐ordered double perovskite hydrides A 2 TiH₆ (A = Li, Na, Be, Mg) were systematically investigated using first‐principles density functional theory to evaluate their structural stability, mechanical performance, electronic properties, and hydrogen storage capabilities for solid‐state energy storage applica...
