Figure 2. (IMAGE) Science China Press Caption (a) Operando Raman measurements. (b) and (c) Operando XPS results of Al 2p and C 1s, respectively. (d) Dependence of intercalated Cl (Clint) and intercalated N (Nint) contents with intercalated Al (Alint) contents. (e) Atomic ratios between intercalated Al (Alint) and host-C (Chost) at different potentials. The theoretical value (dash line) and the concentration in bulk (red and green stars) are displayed for reference.
