[Display omitted] •The intercalation mechanism was employed to improve and resolve the restacking issue in 2D MXene nanosheets.•Supercapacitive performance improved upon the integration of BTO nanoparticles into the 2D multilayered nanosheets of MXene.•The practical application has been studied through glowing LEDs: five red LEDs (each with a 1.8 V forward voltage) and two blue LEDs (each with a 3.6 V forward voltage). 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.
