Argyrodite-type ionic conductors have received significant attention as solid electrolyte systems for all-solid-state batteries due to their high ionic conductivity, mechanical deformability, and processability. However, they often suffer from insufficient rate and cycling performance with high-energy-density metal electrodes, mainly due to chemical and electrochemical instability at low potentials. Herein, we report that incorporating BH4– into the argyrodite structure enhances both lithium ion conductivity and low potential stability. Based on these results, we also develop high-voltage all-solid-state batteries that are reversibly cycled with a high-Ni-content oxide cathode and a lithium metal anode, employing two different argyrodite-type solid electrolytes as the catholyte and anolyte, respectively. The current study suggests that many hydride anions could be promising candidates as coexisting anions in the solid electrolytes of emerging all-solid-state batteries that need to deal with low potential stability.

用于NCM/Li全固态电池的富氢银铜矿固体电解质
银铜矿型离子导体由于其高离子电导率、机械变形性和可加工性，作为全固态电池的固体电解质系统而受到广泛关注。然而，它们通常会因高能量密度金属电极的倍率和循环性能不足而受到影响，这主要是由于低电位下的化学和电化学不稳定性。在此，我们报告将 BH 4 –纳入银汞矿结构中可增强锂离子电导率和低电位稳定性。基于这些结果，我们还开发了可逆循环的高压全固态电池，采用高镍含量氧化物正极和锂金属负极，采用两种不同的银汞矿型固体电解质作为正极电解液和负极电解液，分别。目前的研究表明，许多氢化物阴离子可能是有希望的候选者，作为需要处理低电位稳定性的新兴全固态电池的固体电解质中的共存阴离子。
