Fig. 6

a Voltage profile and exemplary image of negative electrodes harvested from two coated Cu||NMC622, SrF2@Cu||NMC622 and Sn@Cu||NMC622 coin cells after charge for 2 h at 0.2 mA cm-2 or the initial cycle, respectively. Slightly lighter colors indicate a repeated measurement with a nominally identical cell. b Exemplary image and magnified static ex situ 7Li NMR spectra for negative electrodes described in (a). The NMR spectra have been subjected to a phase correction of 0th and 1st order to identify the lithium alloy signal.
