Ti3C2Tx on copper and nickel foams with improved electrochemical performance produced via solution processing for supercapacitor
2018
Herein, we demonstrate the fabrication of Ti3C2Tx electrodes using solution
processing. Two-dimensional (2D) nanometer Ti3C2Tx flakes are
site-aggregated on copper and nickel foam papers with a reconstituted
threedimensional (3D) structure consisting of overlapping and open-pore 2D
flakes. When Ti3C2Tx was used as electrochemical capacitor electrodes in 1M
Na2SO4 solution, the capacitances were comparable to literature values.
There is a quantitative linear relationship between the capacitance and foam
thicknesses. Given the process scalability and the morphological control
that is possible, these results provide a promising road map for convenient
and economical supercapacitors.
