a XRD patterns of the indium foil before and after treatment in the chloroaluminate melt at 190 °C. b Schematic illustration of the three-electrode cell with an indium foil immersed in the electrolyte, a Mo wire as the working electrode (W.E.) and an Al wire as the counter electrode (C.E.) and reference electrode (R.E.). c CV plots of the three-electrode cell at different operation temperatures (scan rate of 2 mV s−1). d The concentrations of indium element in the chloroaluminate melt as measured by inductively coupled plasma optical emission spectrometry. e Schematic illustration of the Al|Mo/In battery configured with an indium foil between two separators in a home-made Swagelok cell. f The voltage profiles of the Al|Mo/In battery at different operation temperatures (0.5 mA cm−2).
