Borohydride-based Solid-state Electrolytes for Lithium Batteries

摘要

Properties of LiBH4-LiCl-P2S5 composites are studied regarding their application as solid-state electrolyte for lithium batteries. The studied materials undergo an amorphization at 60°C, accompanied with Li⁺ conduction increase. The measured ionic conductivity for the optimized borohydride-halide-sulfide system is about ~10⁻³ S cm⁻¹ at room temperature with low activation energies for ions migration suitable for all-solid-state battery applications near room temperature.
