Description
Summary:•A novel porous In2O3/carbon structure was fabricated via annealing an In-MOF precursor.•In2O3/carbon composites were composed of In2O3 nanoparticles embedded in a carbon matrix.•In2O3/carbon composite anode electrode showed excellent cycling stability and rate capability. In order to overcome the disadvantages of low electronic conductivity and large volume variation of pure In2O3 anode material, a novel mesoporous In2O3/carbon composite was fabricated by annealing an indium-based metal-organic framework (In-MOF) precursor. SEM and TEM images demonstrated that In2O3/carbon composites were composed of In2O3 nanoparticles embedded in a carbon matrix due to the calcination of the metal organic framework. Galvanostatic charge/discharge test of the In2O3/carbon composite anode electrode showed a high initial discharge capacity of approximately 1410mAhg−1 and remained a reversible discharge capacity of 720mAhg−1 after 150cycles at the current density of 100mAg−1.
