A general scheme for the preparation of non-spherical anatase TiO2 hollow particles and derived magnetic multifunctional particles by converting hematite cores to magnetite phase is reported (see figure). The TiO2 hollow particles manifest excellent cycling performance and rate capability, confirming their promising application as anode materials for high power lithium batteries.
