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. WebHydride ions have small ionic radii, large electronic polarizability and a high standard redox potential for H 2 /H − (−2.3 V). 10 These characteristics make H − ions promising for applications in next-generation electrochemical energy …
