Hierarchical synthesis of Mo-Sn oxide cage-bell hybrid structures with superior lithium storage.

A facile generic solvothermal alcoholysis strategy is employed to prepare Mo-Sn oxide cage-bell hybrid nanoparticle aggregates. The intrinsic hollow core-shell nature as well as the multi-element characteristics of active components of the unique nanostructures contribute greatly to the enhanced performance as anode materials for lithium ion batteries.
