Engineering chemical-bonded Ti₃C₂ MXene@carbon composite films with 3D transportation channels for promoting lithium-ion storage in hybrid capacitors.

ABSTRACT: Lithium-ion capacitors (LICs) are promising energy storage devices because they feature the high energy density of lithium-ion batteries and the high power density of supercapacitors. However, the mismatch of electrochemical reaction kinetics between the anode and cathode in LICs makes exploring anode materials with fast ion diffusion and electron transfer channels an urgent task. Herein, the two-dimensional (2D) Ti₃C₂ MXene with controllable terminal groups was introduced into 1D carbon nanofibers to form a 3D conductive network by the electrospinning strategy. In such Ti₃C₂ MXene and carbon matrix composites (named KTi-400@CNFs), the 2D nanosheet structure endows Ti₃C₂ MXene with more active sites for Li⁺ ion st
