Origin and Regulation of Self-Discharge in MXene Supercapacitors

Shi Pu et al.

Summary: MXene-based supercapacitors have great potential as electrochemical energy-storage devices due to their high volumetric capacitance, high-power characteristics, and good cyclability. However, they suffer from severe self-discharging behavior and the underlying mechanism is unclear. In this study, the self-discharge behavior of MXene-based supercapacitors is found to be related to the surface electronic structure of MXenes, and a novel method to mitigate this behavior is proposed. By using a bio-thermal treatment, the surface electronic structure of Ti3C2Tx MXenes can be effectively modified, leading to a more than 20% decrease in the self-discharge rate of MXene-based supercapacitors with common aqueous electrolytes. This decrease is attributed to the increased work function and strengthened surface dipole between MXene and electrolytes, resulting in weaker self-discharge kinetics.
