High h− ionic conductivity in barium hydride
WebNd 2 LiHO 3, which has a space group Immm, in which ∼5% of the O sites (2d) are occupied instead by H, had the highest conductivity at 280 °C of 2.2 × 10 −5 S cm −1. The possibility of long-distance H − diffusion in Ln 2 LiHO 3 was computationally investigated. WebOn going to hexagonal symmetry, a regular layered structure emerges, with alternating - "High H⁻ ionic conductivity in barium hydride."
