| Abstract |
Recently, as interest in environmentally friendly renewable energy has increased, a lot of researches have been focused on energy storage systems. Especially, titanium oxide (TiO2) has been actively studied as anode of sodium secondary batteries due to their suitable capacity, reversible cyclability, and electrochemical stability. However, the TiO2 has relatively low electron conductivity. In this study, to overcome low electron conductivity, the nanohybrid between TiO2 and graphene was synthesized to have spherical hollow structure. According to the electron microscopic studies, the nanohybrid was formed to maintain spherical hollow structure. Energy dispersive X-ray analysis showed that the TiO2 and carbon was homogeneously distributed in the nanohybrids. Electrochemical charge/discharge tests clearly showed that the nanohybrids had much larger sodium-ion storage capacity than the bare TiO2. The nanohybrids with enhanced cyclability could be used as anode materials of sodium secondary batteries. |
