An effective strategy to significantly boost the capacitive properties of Fe 2 O 3 ‐based anodes by Ti doping and poly(3,4‐ethylenedioxythiophene) (PEDOT) coating is successfully demonstrated. The Ti‐Fe 2 O 3 @PEDOT electrode exhibits a significant capacitance improvement and exceptionally cyclic stability. A remarkable energy density of 0.89 mWh cm −3 can be obtained for a high‐performance asymmetric supercapacitor device consisting of Ti‐Fe 2 O 3 @PEDOT and a MnO 2 anode.
