Abstract

Abstract : An internally magnetic field was established by CoPt for attracting pulverized ferromagnetic α-Fe2 O3 . Combining with the unique porous structure for accommodating large volume change, the TiO2 /CoPt/α-Fe2 O3 (3DOMTCF) anode demonstrated high reversible capacity and extremely promising cyclic stability. Abstract : A ferromagnetic three-dimensional ordered macroporous TiO2 /CoPt/α-Fe2 O3 (3DOMTCF) nanocomposite was synthesized via a sol–gel approach templated by poly(methyl methacrylate) (PMMA) microspheres. After magnetization, it exhibited an extremely high reversible capacity and a long cycle life, which were ascribed to the internal magnetic field for reusing pulverized active materials and its unique structure.
