Abstract The metal oxide-based materials are expected to be applied to anode material for Li-ion battery because of their high theoretical capacity. However, the metal oxides undergo a large volume change when they react with lithium ions. As the charge and discharge process continues, deterioration of the battery characteristics is occurred such as capacity fading causing by pulverization of electrode. Accordingly, research for developing electrode materials with high capacity and stable cycle properties even at a fast charge and discharge rate is considered to be important. In order to improve the characteristics of the electrode material, studies have been actively carried out to improve the electrochemical properties by reducing the lithium ion and electron transport distance by applying the electrode material with controlled nanostructure, and by improving the electrical conductivity and alleviating the volume change through the formation of composite with various carbonaceous materials. In this research, tin oxide nanoparticles embedded in a porous carbon matrix were synthesized and applied as anode material for Li-ion batteries. The synthesized composite had excellent electrochemical properties due to the advantages of the nanostructure capable of reducing the lithium ion diffusion and electron transfer distance, and the advantage of the carbon composite capable of alleviating volume change during cycling and improving electrical conductivity.
