Highly porous magnesium ferrite hollow spheres are fabricated by a hydrothermal reaction of a composite solution containing magnesium, iron ions, and sucrose giving rise to MgFe-glycolate/carbon microspheres, and subsequently carbon decomposition through thermal process resulting in hollow microspheres. Magnesium ferrite hollow microspheres are composed of nanoparticle-stacked mesoporous shell and macroporous hollow void, which enables electrodes to offer outstanding rate capability and excellent capacity retention by alleviating volume expansion. Magnesium ferrite hollow microspheres possess morphology inducing mass/charge transfer, and structural integrity suppressing the electrochemical decay. |
