  • Large-sized Ti3C2Tx MXene nanosheets (L-MXene, the average lateral dimension was ca. 3.5 μm) were prepared via in-situ etching and mechanical exfoliation, and smaller-sized MXene nanosheets (S-MXene, the average lateral dimension was ca. 0.2 μm) were further fabricated under ultrasonic condition. By controlling the ratio of different sized MXene, a new type of L-MXene/S-MXene was constructed, so as to optimize the stacking structure of MXene layers and shorten the ion transport path. Based on the L-MXene/S-MXene transparent electrode, the assembled flexible transparent zinc-ion hybrid supercapacitors (ZHSCs) achieved large areal capacitance of 8.34 mF·cm-2, high optical transparency of 64.7% and good capacity retention of 93.9% even under 180° bending state.
