MgFe2O4 nanoparticles as anode materials for lithium-ion batteries.

Highlights: [•] MgFe2O4 nanoparticles are prepared by a sol–gel method. [•] The initial discharge specific capacity under the current density of 180mAg−1 reaches 1404mAhg−1. [•] The high specific capacities and good stability were due to its small particle size and the good electrochemical activity. [ABSTRACT FROM AUTHOR]
