a Normalized operando Mo K-edge XANES spectra of architected MoS2 foam electrode measured at different potentials (blue: the discharging process; red: the charging process). b Normalized operando Mo K-edge XANES spectra for the first cycle at open-circuit voltage (OCV, 2.86 V), the first fully discharge (0.01 V), and the first fully charge (3 V) of MoS2, compared with MoO3 and Mo metal foil reference materials. c The cyclic voltammograms of architected MoS2 foam anode at a scan rate of 0.3 mV s−1 and (d) the corresponding absorption edge energy shift (ΔEedge) of architected MoS2 foam at different potentials (labeled as colored dots in the cyclic voltammograms).
