An extremely simple in situ self‐transformation methodology is developed to introduce pseudocapacitance into the MOF system resulting in a largely boosted electrochemical performance: a three‐fold increase in capacitance as well as improved rate capacity. An all‐solid‐state hybrid flexible supercapacitor is fabricated based on the obtained MnO x –MHCF composite and activated carbon with an areal capacitance of 175 mF cm −2 at 0.5 mA cm −2 .
