The demand for efficient post-lithium batteries has steadily increased in recent years. A solution is the utilization of Sodium Ion Batteries (SIBs), as sodium is not only less toxic than lithium but also significantly cheaper. Known compounds for SIB cathodes include layer oxides, polyanionic compounds, or Prussian Blue analogs. So far, it has not been possible to find an universally suitable cathode material in SIBs since sodium behaves similarly to lithium but not identically, for example the significantly reduced diffusion rate of sodium ions due to its larger ion radius compared to lithium ions. The pursuit is to leverage innovative solid-state synthesis techniques in order to identify novel cathode materials for SIBs and ascertain the optimal synthesis pathways. Furthermore, it’s noteworthy that the synthesis methods presented on the poster can be combined with each other, offering additional flexibility and potential for innovative research avenues. The ultimate aim is to meet the rigorous demands for future large-scale production, thereby addressing the inherent challenges posed by sodium’s distinct behavior compared to lithium within the battery system.
