FeMnO₃ (FMO) has received increasing interest as anode material for Li-ion batteries owning to its high theoretical capacity and abundant sources. However, the low electrical conductivity and sluggish kinetics seriously impede its practical application. Herein, nitrogen-doped FeMnO₃ (FMO-N) is prepared by a chemical co-precipitation method and post calcination. Compare to pure FMO, the FMO-N exhibits higher capacity (808 mA h g⁻¹ at 500 mA g⁻¹ after 200 cycles), better rate performance (374 mA h g⁻¹ at 5000 mA g⁻¹), and much enhanced kinetics. Considering the features of low cost and outstanding Li ion storage performance, this FMO-N could be a promising anode material for Li-ion batteries.

FeMnO ₃（FMO）具有很高的理论容量和丰富的来源，作为锂离子电池的负极材料受到越来越多的关注。但是，低电导率和缓慢的动力学严重阻碍了其实际应用。在此，通过化学共沉淀法和后煅烧来制备氮掺杂的FeMnO ₃（FMO-N）。比较纯FMO时，FMO-N显示出更高的容量（808毫安ħ克^-1以500mA克^-1 200次循环后），更好的速率性能（374毫安ħ克^-1在5000毫安克^-1），并大大增强了动力学。考虑到低成本和出色的锂离子存储性能的特点，该FMO-N可以成为锂离子电池的有前途的负极材料。
