Abstract

A new class of Prussian blue analogs, Na₂Ni_xCo_{1 - x}Fe(CN)₆ (0 & x ; 1) with various nickel-to-cobalt ratios (from pure nickel to pure cobalt with a 10% increase in Co content for each sample) was prepared and tested as cathode materials for sodium ion batteries. The Na₂Ni_0.4Co_0.6Fe(CN)₆ sample showed the best electrochemical performance, with an initial discharge capacity of 90 mA h g^{- 1} and reversible capacity of 80 mA h g^{- 1} after 100 cycles. Even at a higher rate of 800 mA g^{- 1}, a good initial discharge capacity of 74 mA h g^{- 1} was obtained.
