| Abstract: | The synthesis of mesoporous Prussian blue analogues through a template‐free methodology and the application of these mesoporous materials as high‐performance cathode materials in sodium‐ion batteries is presented. Crystalline mesostructures were produced through a synergistically coupled nanocrystal formation and aggregation mechanism. As cathodes for sodium‐ion batteries, the Prussian blue analogues all show a reversible capacity of 65 mA h g?1 at low current rate and show excellent cycle stability. The reported method stands as an environmentally friendly and low‐cost alternative to hard or soft templating for the fabrication of mesoporous materials. |
