| Summary: | Currently lithium ion batteries dominate the automotive industry, portable electronic devices and electric grid storage sectors. The limitations of lithium resource and the increasing number of large-scale demand for electricity storage systems have made lithium ion batteries very expensive. An alternative solution to this problem is replacing lithium material to sodium. In this study focused on the synthesis of sodium ion battery anode material. The key to succesfull development of anode material for sodium ion batteries is find material with high capacities and low working potential value. The choice falls on the Na2Ti3O7 compound because it suitably the above requirements. In this final project Na2Ti3O7 compound was synthesized using three different synthesis methods. Material compounds are characterized to determine the crystal structure, surface morphology, and constituent elements. Only one of the three synthesis methods succeeded in obtaining Na2Ti3O7 compound plus other impurities compound such as Na2Ti6O13 and TiO2. Further chemical and thermal treatments are still needed to obtain higher level of purity. |
