a XRD analysis of aluminum negative electrodes in the pristine state (black), after initial full charge (red), after initial full discharge (blue), and after 50 cycles in the discharged state (green). b XRD analysis of Al94.5In5.5 negative electrodes in the pristine state (black), after indium lithiation (partial charge, purple), after full charge (red), after full discharge (blue), and after 100 cycles in the discharged state (green). All cells for (a, b) featured 5.8 mAh cm−2 areal capacity in the positive electrode, lithiating ~70% of the Al foil and ~64% of the Al–In foil in the first charge; testing was performed at 25 °C.
