Oxygen‐deficient α‐Fe 2 O 3 nanorods with outstanding capacitive performance are developed and demonstrated as novel negative electrodes for flexible asymmetric supercapacitors. The asymmetric‐supercapacitor device based on the oxygen‐deficient α‐Fe 2 O 3 nanorod negative electrode and a MnO 2 positive electrode achieves a maximum energy density of 0.41 mW·h/cm 3 ; it is also capable of charging a mobile phone and powering a light‐emitting diode indicator.
