Energy dispersive X-ray diffraction of lithium–silver vanadium phosphorous oxide cells: in situ cathode depth profiling of an electrochemical reduction–displacement reaction

Abstract

Li/Ag2VO2PO4 cells exhibit high power output and a 15 000 fold decrease in impedance upon initial discharge. Energy dispersive X-ray diffraction (EDXRD) allows dimensional resolution of the reaction progress in situ, revealing that silver metal (Ag0) initially forms at the electrode–electrolyte interface. This report contains the first description of an in situ EDXRD analysis of a cathode located within an intact Li-anode cell.
