Impact of Na Concentration on the Phase Transition Behavior and H− Conductivities in the Ba–Li–Na–H–O Oxyhydride System

Impact of Na Concentration on the Phase Transition Behavior and H− Conductivities in the Ba–Li–Na–H–O Oxyhydride System

Abstract K2NiF4‐type Ba–Li oxyhydride (BLHO) transitions to a so‐called hydride superionic conductor, exhibiting a high and essentially temperature‐independent hydride ion (H−) conductivity over 0.01 S cm−1 through the disordering of H− vacancies above 300 °C. In this study, a Ba–Li–Na–H–O oxyhydrid...
