Preparation and Electrochemical Performance Analysis of MXene/Coconut Shell Carbon Composite Materials
MXene has a band structure similar to metallic materials and exhibits good conductivity.However,MXene is prone to layered stacking,which affects the electrochemical performance of MXene materials.This study aims to prepare MXene composite materials by mixing MXene and coconut shell carbon in deionized water,and investigate the effects of its structure and morphology on its electrochemical properties.The research results indicate that soluble coconut shell charcoal added to MXene films promotes the migration of lithium ions through interpenetration between particles.The charging and discharging experiments were conducted on the material,and the results showed that using a 1∶2 mass ratio of material,under a current density of 0.1 A/g,its initial charging and discharging specific capacity can reach 1 951.7 mAh/g.After 200 cycles,its charging and discharging specific capacity is 800.8 mAh/g.
