Herein, a new quasi-elliptic nanostructure of composite composed of innermost quasi-elliptic TiO2, outmost carbon coating and sandwiched SnO2 nanoparticles has been successfully fabricated by a well-designed approach for the first time. This unique architecture provides the structural stability of SnO2 nanoparticles with double assurance, as well as improves the conductivity of whole composite. As a result, the as-prepared TiO2/SnO2/C composite exhibits superior lithium storage. Moreover, the preparation of elliptic TiO2/SnO2/C composite can further enrich the variety of the morphologies of TiO2/SnO2/C composites.
