英文摘要	Carbon modified porous γ-Fe2O3 particles (PFe2O3–C) are synthesized by a high temperature calcination method using sodium chloride as a template. During the nucleation and carbonation process, the Fe(NO3)3–C10H15N5 complex uniformly dispersed on the surface of NaCl particles which can limit its longitudinal growth, thus forming independent and homogeneous nanoparticles with a diameter of about 30 nm. Because of this special structure, the γ-Fe2O3 particles have a sufficient interspace between them, which can not only provide a large number of active sites for storing lithium ions, but also shorten diffusion length for lithium ion transport. The introduction of carbon can offer additional lithium ion storage and improve overall electrical conductivity. This PFe2O3–C electrode exhibits excellent rate performance (1139, 1067, and 972 mAh g−1 at 2, 5, and 10 C, respectively, 1 C = 924 mAh g−1) and cycle performance (up to 2100 mAh g−1 after 200 cycles at 0.3 C). © 2018, Springer Science+Business Media, LLC, part of Springer Nature.
