Non-aqueous synthesis of high-quality Prussian blue analogues for Na-ion batteries

A microwave-assisted solvothermal (MW-ST) method was developed to synthesize high-quality Prussian blue analogues. The tuned NaFeHCF exhibits low water content as well as good thermal stability. It delivers a high initial discharge capacity of 150 mA h g −1 , good rate capability and cycling life ov...

Zusammenfassung:A microwave-assisted solvothermal (MW-ST) method was developed to synthesize high-quality Prussian blue analogues. The tuned NaFeHCF exhibits low water content as well as good thermal stability. It delivers a high initial discharge capacity of 150 mA h g −1 , good rate capability and cycling life over 500 cycles. A novel non-aqueous MW-ST method has been developed for the synthesis of high quality Prussian blue cathodes for Na-ion batteries.
