Abstract

Abstract: Solid-state electrolyte (SSE) coupled with Li metal anode, is one of the very promising architecture designs to achieve all-solid-state batteries (ASSBs) for advanced next-generation energy storage technology in expectation of boosted energy density, power, and increased safety. Among the reported SSEs, the garnet-type Li7 La3 Zr2 O12 (LLZO) SSEs have attracted wide interest in terms of their relatively high ionic conductivity and good chemical stability against Li metal. However, there is an increasing amount of recent research pointing out the interfacial (electro)chemical instabilities between LLZO and electrodes (Li anode and cathode), which hinder their commercial-scale applications. In this review, we introduce the interfacial stability challenges at both LLZO/Li anode and LLZO/cathode interfaces revealed by recent works. We also review and summarize the diverse interfacial designs on mitigating such instabilities, and in situ characterization techniques to understand these interfacial issues.
