A nano-composite material with improved performance was developed by modifying the structure of Prussian blue and utilizing electron exchange between graphene oxide and PB. It exhibited excellent properties as a cathode in sodium-ion batteries.
A micro-cubic Prussian blue (PB) with less coordinated water is first developed by electron exchange between graphene oxide and PB. The obtained reduced graphene oxide-PB composite exhibited increased redox reactions of the Fe sites and delivered ultrahigh specific capacity of 163.3 mA h g(-1) (30 mA g(-1)) as well as excellent cycle stability as a cathode in sodium-ion batteries.
