In recent years, due to its high conductivity and surface hydrophilicity, good ion transfer performance and excellent mechanical properties, MXene has received extensive attention and made some progress in the field of energy storage, among which the research on Ti3C2Tx MXene materials is the earliest and most common. In this paper, MXene films with the same quality was prepared by spraying method on cellulose paper, ordinary A4 paper, smoother filter paper and coarse filter paper, and the thin films with different thickness was sprayed on the same paper substrate. Then the same shape of finger pattern was carved by laser engraving machine and finally was assembled into microsupercapacitor. The electrochemical properties of MXene based microsupercapacitors were tested to reveal the effects of different thickness and paper substrate on the electrochemical properties of MXene based microsupercapacitors (MSCs). The areal capacitance of a single device can reach 78 mF/cm2, and the energy density is as high as 14.1 mWh/cm2 at the power density of 115.5 mW/cm2. Four devices connected in series can drive a clock.
