Graphical abstract: Hierarchically heterostructured TiO{sub 2}@SnO{sub 2} core-branch nanofibers are synthesized with promising electrochemical performance as anodes for lithium-ion batteries. - Highlights: • TiO{sub 2}@SnO{sub 2} core-branch nanofibers are synthesized by a facile method. • The hybrid TiO{sub 2}@SnO{sub 2} nanofibers exhibt large capacity and good cycle performance. • The hybrid TiO{sub 2}@SnO{sub 2} nanofibers can be promising anode materials for lithium-ion batteries. - Abstract: Hierarchically heterostructured TiO{sub 2}@SnO{sub 2} core-branch nanofibers are synthesized by a facile method using electrospinning followed by a hydrothermal treatment. By carefully controlling the TiO{sub 2} content in the composite, a hierarchical heterostructure featuring uniform growth of rutile SnO{sub 2} nanocubes on the surface of anatase TiO{sub 2} nanofibers can be obtained. The hierarchically branched TiO{sub 2}@SnO{sub 2} nanofibers combine both advantages of SnO{sub 2} with large specific capacity and TiO{sub 2} with outstanding structural stability. The TiO{sub 2} content plays an important role in determining both the morphology and electrochemical performance of the composite. It is found that the TiO{sub 2}@SnO{sub 2} nanofibers with 30 wt% TiO{sub 2} exhibit both large specific capacity and good cycling stability, making them promising as anodes for high performance lithium-ion batteries.
