Abstract

Solid-state batteries offer an alternative promising power source for electric vehicles. However, the interfacial mechanical stability of inorganic electrolytes is inferior to that of organic electrolytes. A high stack pressure (several to hundreds of megapascals) is often required to maintain intimate contact with electrodes. Here we report a class of viscoelastic inorganic glass (VIGLAS) to serve as solid electrolytes by simply replacing chlorine of tetrachloroaluminates with oxygen. The VIGLAS possesses high ionic conductivity (~1 mS cm−1 at 30 °C) for both Li+ and Na+, superior chemo-mechanical compatibility with 4.3 V cathodes and the ability to enable pressure-less Li- and Na-based solid-state batteries (
