How It Compares
Within the layered sodium transition-metal oxides class.
Within the broader family of layered sodium transition-metal oxides, Na5Mn7O16 occupies a specialized niche compared to more common, highly stable phases like NaCoO2 or NaFeO2. While many siblings in this class are studied for their robust cycling capabilities, this manganese-rich oxide is distinguished by its metastable nature, which provides a different structural framework for studying ion insertion processes compared to the simpler, more conventional layered structures.
