Mn-based sodium superionic conductor (NASICON) phosphate cathodes have been considered as new promising candidates for high-energy, low-cost and relatively environmentally friendly sodium-ion batteries (SIBs). Such cathodes, however, suffer from limited Na + mobility owing to rigid coordinated envir...
