摘要：
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 MnOx-MHCF composite and activated carbon with an areal capacitance of 175 mF cm(-2) at 0.5 mA cm(-2).
