摘要

研究了LiBH4-LiCl-P2S5复合材料作为锂电池固态电解质的性能。材料在60℃时发生非晶化，同时Li+导率增加。优化后的硼氢化物-卤化物-硫化物体系在室温下的离子电导率约为~10−3 S cm−1，离子迁移活化能低，适合于室温下的全固态电池应用。

Borohydride-based Solid-state Electrolytes for Lithium Batteries

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.
