Enhanced electrochemical energy storage performance by mediating BaTiO3 nanoparticles into the multilayers of Ti3C2Tx MXene

Abstract

MXenes belong to the family of two-dimensional (2D) transition metal carbides, have been identified as advanced energy materials with exceptional performance. In this paper, we employed a strategy to intercalate BaTiO3 (BTO) nanoparticles into the two-dimensional (2D) Ti3C2Tx MXene sheets and use as electrode materials for electrochemical performances. BTO intercalated MXenes prove more active areas for improved electrochemical performance. As a result, the BTO intercalated Ti3C2Tx MXene electrode exhibits a high specific capacitance of 254.28F/g at 1 A/g and a retention ratio 74% after 10,000 cycles. The electrochemical stability study confirms that restacking issues were resolved. Thus, the intercalation of BTO enhanced the reaction kinetics of the MXenes and facilitate the charge storage valuable mechanism for next-generation smart energy storage devices.
