Manganese-based Prussian blue (MF-N) is a promising cathode material for sodium-ion batteries and has attracted wide-spread attention owing to its advantages of high specific capacity and low cost. However, the lattice channel instability of MF-N during sodium ion de-intercalation leads to drastic p...
