A uniform and stable precursor spinning solution was prepared by using polyvinylpyrrolidone (PVP), ferric nitrate nonahydrate and manganese acetate tetrahydrate as raw materials, anhydrous ethanol and N,N-dimethylformamide as solvent, followed by magnetically stirred. The PVP/Mn(COOH)₂/Fe(NO₃)₃ composite nanofibers were prepared by electrospinning technology. FeMnO₃ nanofibrous mats were obtained after high temperature calcination, which was used as anode material for lithium battery. Apparent morphology and crystal structure of the samples were investigated by FT-IR, XRD, SEM, and BET specific surface area analyzers. All results showed that the fabricated FeMnO₃ nanofibrous mats possessed good structural morphology with the specific surface area of 9.9 m ²/g. TG analysis showed that when temperature reaches 470 ℃, the TG curve becomes gentle while the mass loss is not obvious. Results form charge and discharge, cyclic voltammetry, and cycle performance tests, indicated that FeMnO₃ nanofibrous mats had good electrochemical performance and electrical stability, with a specific capacity of 533 mAh/g at 50 mA/g after 37 cycles. After 50 cycles, the impedance is approximately 170 Ω, which remains essentially unchanged.
