Abstract

In this study, a reduced graphene oxide-supported Na_3.12Fe_2.44(P₂O₇)₂/C nanocomposite was successfully synthesized by a sol–gel method and a subsequent heat-treatment process. Not only did the composite undergo a highly reversible electrochemical reaction, but it also exhibits superior rate capability and long-term cyclic stability as a Na-ion battery cathode.
