Sodium and potassium iron hexacyanoferrate nanoparticles were synthesized by coprecipitation method. As-prepared nanoparticles were employed as cathode materials for lithium and sodium rechargeable batteries. Utilizing a well-defined Prussian blue structure exhibits high cyclic stability. In particular, NaFeHCF NPs deliver the reversible capacities of 104 and 109 mAh/g at a current density of 100 mA/g for lithium and sodium battery applications, respectively.
