Rechargeable all-solid-state Li batteries with solid electrolytes (SE) are a prospective solution for safe and high capacity energy storage systems. In recent decades, several types of SE with high ionic conductivity have been developed and tested with different techniques. In this study, we employed a non-destructive nuclear analytical method, Neutron Depth Profiling (NDP), to investigate the response of one of the promising electrolytes, Lithium Conductive Glass Ceramic (LICGC), to the applied voltage +2.8 V. The in-situ NDP measurements made it possible to directly monitor the migration of lithium ions in the electrolyte and to observe and quantify the formation of a space charge layer with depleted Li atoms, which depends on the biasing time.
