This study shows that heat-treatment of colloidal inorganic nanoplates with columnar assembly under argon is a good strategy for development of anode materials. The heating of colloidal In2S3 nanoplates under argon resulted in the formation of film-like materials through interconnection of plates side by side because the plates had a strong preference for growth in the vertical direction to the basal plane. When the columnarly assembled colloidal In2S3 plates were heated at 400 oC under argon for 2 hours on graphene, more efficient anode materials with smaller diameters were obtained. Interestingly, the heat-treated columnarly assembled In2S3 plates on graphene had a layered structure, which was attributed to the possible existence of carbon materials between plates formed by the heat-treatment of surfactant under argon. The heat-treated graphene-In2S3 composites showed enhanced discharge capacities, up to 716-837 mAh/g as well as excellent stabilities. In addition, the materials showed promising columbic efficiencies and rate performances. We believe that, based on the strategy in this work, diverse graphene-inorganic nanomaterial composites with a layered structure can be prepared and applied as new anode materials in lithium ion batteries.
