NiCo oxyfluoride non-woven cloth with ultra-high area capatitance for wearable supercapacitors
Supercapacitors,which serve as a kind of novel energy storage devices,are proven a promising solution for developing miniaturized,flexible,wearable electronics.Lightweight thin film electrodes that can be implemented is a potential developing orientation.Nevertheless,insufficient device energy density impedes its practical applications.To elevate device energy density,complicated assembly of nanostructured two-dimensional electrodes is a useful technique but results in high cost.Herein,we report a magnetic-assisted technology to fabricate tailorable,tractable,and flexible NiCo oxyfluoride non-woven cloth(NOC)for cathode,which can reveal superior electrochemical performance and excellent mechanical flexibility.A superb high areal capacitance up to 3.07 F cm-2 and no significant capacitance decay after 5000 cycles reveal the great potential in practical applications of the NOC electrodes.
