All-solid-state lithium batteries (ASSLBs) are in urgent demand for future energy storage. The basic problems are, however, low ambient-temperature ionic conductivity and narrow electrochemical windows of solid electrolytes as well...
Despite excellent ionic conductivity and electrochemical oxidative stability, the emerging halide-based solid electrolytes suffer from inherent instability toward Li metal anode. A thick and resistive interface can be formed by...
