High-capacity freestanding supercapacitor electrode based on electrospun Ti 3 C 2 T x MXene/PANI/PVDF composite

In this study, a high-capacity freestanding supercapacitor electrode was developed through electrospinning of a Ti C T MXene/Polyaniline (PANI)/Polyvinylidene fluoride (PVDF) composite. MXene/PANI composite was achieved through a facile synthesis in which Ti C T was mixed with PANI Emeraldine salt i...

description In this study, a high-capacity freestanding supercapacitor electrode was developed through electrospinning of a Ti C T MXene/Polyaniline (PANI)/Polyvinylidene fluoride (PVDF) composite. MXene/PANI composite was achieved through a facile synthesis in which Ti C T was mixed with PANI Emeraldine salt in N-Methyl-2-Pyrrolidone (NMP) solution using magnetic stirring. PVDF was added to the composite as a flexible binder to facilitate the electrospinning and produce a freestanding electrode. The specific capacitance of the freestanding MXene/PANI/PVDF electrode is 740 Fg at a scan rate of 2 mVs , and 895 Fg at a charge-discharge current density of 0.5 Ag , which was significantly higher than the specific capacitance of MXene (67 Fg ) and PANI (54 Fg ) electrospun electrodes.
