Effects of Anion Clusters at Solid-State Electrolyte and Electrode Interfaces

Abstract

Stability and transport properties at the electrolyte-electrode interface are of great importance to the performance of all-solid-state batteries with solid-state electrolytes (SSEs). Most recent studies have shown that mono-/poly-anion clusters that are either original contained or doped in the SSE can lead to intriguing (transport, electronic, and mechanical) properties [1-6]. However, the effects of anion clusters on the SSE-electrode interfaces are unknown. Here, we will investigate such effects and unravel the working mechanisms using phase/reactivity analysis and explicit interface modeling.
