Synthesis of Na2MnFe(CN)6 and its Application as Cathode Material for Aqueous Rechargeable Sodium-ion Battery.

Prussian Blue type Na₂MnFe(CN)₆ was prepared by direct precipitation method and a subsequent drying procedure as a cathode material for aqueous rechargeable sodium-ion batteries. XRD patterns showed that Na₂MnFe(CN)₆ has a typical Prussian Blue structure with space group Fm3m. Na₂MnFe(CN)₆ presents good electrochemical behaviors at 10 mAg^-1 discharge current density with specific capacity 73.1 mAhg^-1 after 30 cycles. The results show that Na₂MnFe(CN)₆ could be a potential cathode material for aqueous Sodium-ion battery. [ABSTRACT FROM AUTHOR]
