近年来，钠离子电池正极材料的发展非常迅速。本工作提供了用溶剂热法制备的钠离子电池正极材料Fe-3(PO4)(2)。用第一性原理研究了其结构和电子电导。钠离子电池在25 mA g(-1)的电流密度下循环11次，容量高达223.0 mA h g(-1)。这表明，Fe-3(PO4)(2)微材料将是一种非常有前途的钠离子电池正极候选材料。
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.
