Herein, we prepared the Bi 2 O 3 nanoflowers decorated MXene electrode via the coprecipitation method. The insertion of Bi 2 O 3 nanoflowers over the MXene nanosheet not only effectively resolves the restacking challenge of the MXene nanosheet but also improves the overall electrochemical performance of the MXene/Bi 2 O 3 nanocomposite. The fabrication of an MXene/Bi 2 O 3 //MnCo 2 O 4 supercapacitor device used for powering portable electronic devices confirmed that the lab-scale innovation could be turned into practical energy technologies. This work highlights a room-temperature synthesis strategy for the MXene-based nanocomposite, leading to high-performance, laboratory-scale prototype energy storage devices. Furthermore, this self-assembly process of MXene-metal oxide nanocomposites at room temperature opens new avenues for energy storage applications.
