Highly efficient MoS₂ quantum sheets for next generation self-charging power cell

다국어 초록 (Multilingual Abstract)

The development of self-charging power cell (SCPC) can be a potential candidate for solving the problem of supplying power to microelectronics devices. Herein, we focus on the designing and development of portable and wearable self-charging power cell via utilizing the 1TMoS₂ QSs as an energy harvesting and storage material. The fabricated MoS₂ quantum sheets-based planer micro-supercapacitors (MoS₂ QSs MSC) via a single-step laser engraving process indicated superior energy density, tailored capacitance and exceptional shape diversity aptitude. Again, triboelectric nanogenerator introduced with 1T-MoS₂ QSs based charge trapping/blocking layer enhances the output voltages and power density of TENG significantly, which is 13-fold higher than that of pristine TENG. Furthermore, we have fabricated all in one MoS₂ based SCPC which showed their superior self-charging ability up to 1.1V externally, Overall, this work creates a way for developing highly efficient next generation battery free wearable and portable electronics.
