(a) Capacity–voltage profiles and the corresponding differential capacity plots (inset) of LC/Li cells. (b) GITT profiles of the LC/Li cells. (c–e) Ex situ analyses of LC electrodes at different states of charge during battery cycling. (c) XPS local scan spectra of Li 1s, N 1s and O 1s regions, (d) FTIR spectra of CN and CO bonds and (e) emission spectra are reversibly switching on reduction and oxidation of the LC, which is indicative of the redox stability of alloxazinic systems.
