An easily manipulated protocol for patterning of MXenes on paper for planar micro-supercapacitors

An easily manipulated protocol for patterning of MXenes on commercial printing paper for planar micro-supercapacitors is reported, with which the fabricated devices can acquire a maximal areal capacitance of 27.29 mF cm⁻², achieving at least 460% enhancement compared to the value of advanced carbon-based planar MSCs (0.1–6 mF cm⁻²).
