Abstract:

With the increasingly serious energy and environmental problems, the development of green energy storage and conversion technologies becomes more and more crucial. As an environmentally friendly energy storage device, the rapid development of the sodium-ion batteries(SIBs) has stimulated the demand for high-performance cathode materials. Among various kinds of cathode materials, amorphous iron phosphate(FePO4) has attracted enormous attention as a promising cathode material for sodium-ion batteries because of its high theoretical specific capacity and superior electrochemical reversibility. Herein, this review is focused on recent advances in amorphous FePO4 for sodium-ion battery cathodes. First, the common characteristics and applications of amorphous FePO4 are introduced. Next, the synthesis methods are summarized, including template synthesis, hydrothermal synthesis and some other methods. Subsequently, the research progress of strategies to improve sodium-ion storage properties is introduced in detail, with an emphasis on the relationship between structure and performance. Finally, the conclusion and prospects in this field are discussed.
