Enhancing lithium ion storage property of FeMnO3 as an anode material via N doping
2021
Abstract 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.
