摘要：

In the work, the porous FeMnO3 nanocages combined with nitrogen-doped carbon shells (FeMnO3@NC) are studied as the anode material for lithium ion batteries (LIBs). The FeMnO3@NC composite can inherit the nanocage-like structure of Prussian blue analogue (PBA) precursor, which is capable of buffering volume expansion and promoting the penetration of electrolyte. The nitrogen-doped carbon layer enhances the electronic transmission and structure stability of perovskite-type FeMnO3. Therefore, the composite electrode exhibits superior electrochemical performances, including desirable rate capability, excellent cycling stability and high capacity of similar to 1008 mAh g(-1) after 500 cycles at 1 A g(-1). Considering the features of FeMnO3@NC composite with environmental friendliness, low cost, and outstanding lithium ion storage performance, it is expected to become a promising material for new hybrid energy storage devices.
