Abstract: Iron‐manganese‐based polyanionic compounds (Na4Fe3‐xMnx(PO4)2P2O7) have attracted extensive interest as cathode for sodium ion batteries (SIBs) owing to higher working voltage, and higher energy density compared to Na4Fe3(PO4)2P2O7. However, such cathode suffers from sluggish Na+ diffusion,… read more here.
