Cylindrical janus Mosse@CNT intercalated into Mxene: A high-performance supercapacitor electrode with high volumetric capacity and flexibility
Source abstract
Abstract
Restoring MXene’s intrinsic capacitive function is essential for high-performance supercapacitors. This study presents a new approach to tackle the problem of restacking and improving energy storage. It involves incorporating MoSSe@CNT (MoSSe nanosheets wrapped around carbon nanotubes) into MXene films, which are exceptionally electrochemically active. After optimisation, the MoSSe@CNT/MXene electrode demonstrates remarkable volumetric and gravimetric capacitance values of 1819 F cm⁻³ and 585 F g⁻¹, respectively. The exceptional performance of MoSSe@CNT arises from the combined effects of MoSSe@CNT acting as both spacers and active contributors to pseudocapacitance. The electrode obtained exhibits exceptional rate capability, flexibility, and a high energy density of 47.5 Wh L⁻¹, making it a highly promising contender for advanced energy storage systems.
