FeSe2 microspheres assembled by nano-octahedra are used as an anode material for Na-ion batteries for the first time, showing a high discharge capacity (447 mA h g(-1) at 0.1 A g(-1)), excellent rate performance (388 mA h g(-1) at 5 A g(-1) and 226 mA h g(-1) at 25 A g(-1)), and long cycling stability (372 mA h g(-1) after 2000 cycles at 1 A g(-1)).
首次将 FeSe2 纳米八面体组装的微球用作钠离子电池的阳极材料，展现出高放电容量（在 0.1 A g-1 时为 447 mA h g-1）、优异的倍率性能（在 5 A g-1 时为 388 mA h g-1，在 25 A g-1 时为 226 mA h g-1）和长循环稳定性（在 1 A g-1 时经过 2000 次循环后为 372 mA h g-1）。
