Abstract:
There is a need to develop cost-efficient and high-performance large-scale batteries for intermittent energy sources. In this regard, sodium-ion batteries (SIBs) have emerged as a potential candidate for the use of electrical energy storage systems (ESS), which share similar electrochemical principles to the comparatively high-cost lithium-ion batteries (LIBs). However, high-performance electrode materials are required for the realization of SIBs.
In this presentation, the development of anode materials for SIBs will be discussed. Our group has contributed to a variety of materials such as carbonaceous, intercalation-based metal oxides, conversion-based metal oxides, and alloying materials as anodes for SIBs. The results show that novel carbon-based anodes possess the capability of high energy and power density. The intercalation-based anodes such as TiO2 have also shown good stability over long cycling, thus demonstrating the suitability as anodes for SIBs. Conversion-based metal oxides also show promising electrochemical properties when used as a full sodium-ion cell. Finally, the nano-sized alloying-based SnF2 material was tested as anodes, and the electrochemical results, as well as the reaction mechanism of the material using synchrotron-based X-ray absorption spectroscopy, are measured. All of the above will be discussed in detail during the talk.
