Interfacial chemistry of all-solid-state batteries

All-solid-state batteries are the next generation battery technology, with the hope to replace the current liquid electrolytes for increased safety and higher energy density, if lithium metal anodes and solid electrolytes are used. In order to assess the performance and future of all-solid-state batteries we investigate the occurring interfacial processes using in situspectroscopic techniques and time-resolved electrochemistry.
