Selective edge etching to improve the rate capability of Prussian blue analogues for sodium ion batteries

Prussian blue analogues (PBA) possess a high theoretical specific capacity for sodium ion batteries. However, cycling PBA to a high current density causes severe capacity fading. Here, we develop a selective edge-etching approach to tackle this long-standing issue of poor rate capability. Well-cryst...
