Description
Summary:Monodisperse C/In2O3 nanosheet composites are prepared by D-fructose-assisted solvothermal approach. The effects of carbon content on the morphological evolution and electrochemical performance of C/In2O3 nanosheet composites are investigated. The SEM and TEM are used to study the morphological evolution. C/In2O3 nanosheet composite electrode with 17.3% carbon content exhibits the highest reversible capacity of 1639 mAh g-1 over 100 cycles at a current density of 100 mA g-1 and maintains the best discharge capacity of 782 mAh g-1 over 400 cycles at a current density of 400 mA g-1 for reported In2O3 based anode materials to date.
