In Situ Formed Li–B–H Complex with High Li-Ion Conductivity as a Potential Solid Electrolyte for Li Batteries
Source abstract
Abstract
Li–B–H complexes facilely prepared via partial dehydrogenation of LiBH4 are presented in this study as solid electrolytes for Li batteries. An exceptionally high Li-ion conductivity is found for the Li–B–H complex with 7.5 wt % H2 desorption under 3 bar H2 pressure, which reaches 2.7 × 10–4 S cm–1 at 35 °C, more than 4 orders higher than that of LiBH4. In-depth characterizations show that LiH and [Li2B12H11+1/n]n are in situ formed in the LiBH4 matrix and the interface layer between [Li2B12H11+1/n]n and LiBH4 is believed to be responsible for the high Li-ion conductivity. Moreover, this Li–B–H complex also exhibits excellent electrochemical stability, which enables the stable cycling of all-solid-state batteries at room temperature.
