摘要

Porous structured MgFe2O4 particles were successfully prepared via a simple and low-cost route by sol–gel combustion synthesis. The final product was characterized by X-ray diffraction (XRD) and scanningelectron microscopy (SEM). The average diameter of the prepared MgFe2O4 particles was found to beapproximately 41 nm. When used as an anode material of lithium ion batteries (LIBs), MgFe2O4 showedan excellent cycling performance and a fairly high rate performance. The good Li storage performancecan be attributed to the uniform porous structure without impurities that accommodates the strain due tothe volume change in the charge/discharge cycles and expands the active area for lithium ion insertion.Additionally, the Na storage properties of MgFe2O4 as an anode material of sodium ion batteries werestudied, and similar characteristics to those of LIBs were obtained during the discharge/charge cycles,with a high capacity in the initial discharge process but relatively moderate capacity retention comparedto that found in the study of Li storage properties.
