Abstract

Herein, MnO₂ nanoflowers are electrodeposited on a self-supported and electroconductive electrode in which 2D Ti₃C₂T_x nanosheets are encased in carbon nanofibers (MnO₂@Ti₃C₂T_x/CNFs). This improves the conductivity and hydrophilicity of the MnO₂ composite electrode. The asymmetric supercapacitor shows a high energy density of 46.4 W h kg⁻¹ and a power density of 4 kW kg⁻¹.
