Interconnected quasi-nanospheres of SnO2/TiO2/C with gap spaces for improved lithium storage

Herein, by combining the advantages of SnO2, TiO2 and carbon elaborately, we present a stable nanostructure of SnO2-based composite. As a promising anode for lithium-ion batteries (LIBs), it delivers a high capacity of 642.5 mAh g−1 after even 450 cycles, exhibiting outstanding lithium storage performance. This work provides a facile and effective method for addressing the undesirable volume variation issue of SnO2 anodes.
