Abstract

Lithium borohydride (LiBH₄) is a candidate material for a solid electrolyte of all-solid-state lithium secondary batteries. In this study, the hydration behavior and influences of hydration on the ionic conductivity of LiBH₄ were investigated. LiBH₄ was found to become hydrated without decomposing; structural water can dehydrate at 55 °C and then rehydrate at around 35 °C. Hydrated LiBH₄ has a high lithium-ion conductivity of 4.89 × 10^{- 4} S.
