title: Prussian blue: a new framework of electrode materials for sodium batteries.
abstract: Prussian blue and its analogues consisting of different transition-metal ions (Fe, Mn, Ni, Cu, Co and Zn) have been synthesized at room temperature. Insertion of Na into KFe(2)(CN)(6) in a carbonate electrolyte exhibited a reversible capacity near 100 mA h g(-1) with no capacity fade in 30 cycles. The data indicate that a Na-ion battery with a Prussian blue framework as a cathode will be feasible.
