Sodium super ionic conductor (NASICON) based electrode and electrolyte compounds offer new prospect to achieve higher energy/power densities, improved safety, and longer cycle life in sodium ion batteries (SIBs). For many years NASICON compounds have not been regarded as a possible electrode material for SIBs, mainly because, the research was focusing on the electrolyte aspect. However, in recent years NASICON type materials have attracted a great deal of attention as an electrode as well due to their excellent properties, which include high io...
