A micro-cubic Prussian blue (PB) without coordinated water is first developed by electron exchange between graphene oxide and PB. The obtained reduced graphene oxide-PB composite exhibited complete redox reactions of the Fe sites and delivered ultrahigh electrochemical performances as well as excellent cycling stability as a cathode in sodium-ion batteries.
一种无配位水的微立方普鲁士蓝(PB)首先通过氧化石墨烯与PB之间的电子交换制备而成。所获得的还原氧化石墨烯-PB复合材料表现出铁位点的完全氧化还原反应,并作为钠离子电池的阴极展现出超高的电化学性能以及优异的循环稳定性。
