Cu-MOF及其衍生物负极材料的制备及结构研究
Preparation and structural study of Cu-MOF and its derivative anode materials
摘要
Abstract
Hollow porous CuO/C-350 composite microspheres were successfully obtained by pyrolyzing Cu-MOF(metal-organic framework).Scanning electron microscope(SEM)images revealed that the prepared target material exhibits porous characteristics.In situ small-angle X-ray scattering(SAXS)tests showed the structural evolution of the CuO/C-350 electrode material during the first charging and discharging cycle.Electrochemical tests were conducted using CuO/C-350 as the anode material for lithium-ion batteries,with results indicating that these microspheres can maintain a high reversible capacity of 709.5 mAh·g-1 after 100 charge-discharge cycles at a current density of 100 mA·g-1.This excellent electrochemical performance is attributed to the hollow porous structure of the material and the good conductivity of the residual carbon material.Notably,even at a high current density of 500 mA·g-1,this material still provides a reversible capacity of 641.3 mAh·g-1,demonstrating its ability to maintain good rate capability under high-rate charge-discharge conditions.This porous structure offers more storage space and faster transport channels for lithium-ion,making CuO/C-350 composite material a promising anode material for lithium-ion batteries.关键词
