Figure 1 | MXene electrodes. a, Schematic illustration of MXene structure. MXenes possess excellent conductivity owing to a conductive carbide core along with transition metal oxide-like surfaces
Figure 2 | Electrochemical performance of planar MXene electrodes. a, Cyclic voltammetry profiles for Ti 3 C 2 T x electrode collected at 5 mV s − 1 in 3 M H 2 SO 4 at different potential windows on a glassy carbon current collector
Figure 3 | Electrochemical performance of macroporous Ti 3 C 2 T x electrodes. a, Cyclic voltammetry profiles of a macroporous 13-µm-thick film with a 0.43 mg cm − 2 loading collected in 3 M H 2 SO 4 at scan rates from 20 to 10,000 mV s − 1
