普鲁士蓝及其由不同过渡金属离子(Fe、Mn、Ni、Cu、Co 和 Zn)组成的类似物已在室温下合成。将Na插入碳酸盐电解质中的KFe2(CN)(6)中,表现出接近100 mAh g(-1)的可逆容量,并且在30个循环中没有容量衰减。数据表明,以普鲁士蓝骨架作为阴极的钠离子电池是可行的。
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 KFe2(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.
