摘要：

In recent years, the development of cathode materials for sodium-ion batteries is very rapid. This work provides the Fe-3(PO4)(2) micromaterials fabricated by the solvothermal method for sodium-ion battery cathode. The structure and the electronic conductivity were investigated by the first-principle. Sodium-ion battery exhibits excellent capacity of 223.0 mA h g(-1) at the current density of 25 mA g(-1)after eleven cycles. This reveals that the Fe-3(PO4)(2) micromaterials will be a remarkably promising cathode candidate for sodium-ion batteries.
