Electrochemical performance of 2D IE‐MXene electrodes including a) CV curves at scan rates of 1–20 mV s⁻¹, b) GCD curves at current densities of 0.4‐8 A g⁻¹. c) Gravimetric capacitances calculated from CV curves as a function of scan rates and d) Cycling stability at a current density of 4 A g⁻¹ (Inset shows the first and last ten GCD curves).
