Abstract

VN usually has poor rate performance and cycle stability. In this work, porous VN nanosheet arrays were prepared on carbon nanofibers embedded with Ti₃C₂T_x nanosheets by electrospinning and chemical vapor deposition. The 3D network accelerates the transfer of electrons and electrolyte ions, prevents the aggregation of VN and the self-stacking of MXene, and enhances cycle stability. The solid-state flexible device comprising Co₃O₄, MXCF@VN, and KOH/PVA exhibits exceptional energy densities of 83.95 W h kg⁻¹ and robust cycling stability (82.8% retention after 20 000 cycles). © The Royal Society of Chemistry 2024.
