Title: Flexible MXene/Carbon Nanotube Composite Paper with High Volumetric Capacitance

Electrochemical capacitors attract attention because of their high power densities and long cycle lives. Moreover, with increasing demand for portable and wearable electronics, recent research has focused primarily on improving the energy density per unit of volume of electrochemical capacitors. But, the volumetric capacitances of carbon-based electrodes is limited at around 60 F cm -3 for commercial devices, and at best in the range of 300 F cm -3 for low-density porous carbons (<0.5–1 g cm -3 ). Although extremely high capacitances of 1000–1500 F cm -3 can be achieved for hydrated ruthenium oxide, RuO 2 , its high cost limits its wide-spread applications.
