In order to investigate the reaction products of the halide solid electrolyte Li3InCl6 with lithium, lithium is applied to the electrolyte by sputter deposition. In situ X-ray photoelectron spectroscopy (XPS) is used to investigate the resulting decomposition products. It was found that Li3InCl6 decomposes into In2O3 and indium metal, among others. Since indium metal is electronically conductive, the electrolyte will decompose until either Li3InCl6 or the lithium is depleted, thus the electrolyte cannot be used in direct contact with lithium.
