SnO 2 -based materials have been widely studied because of their high theoretical specific capacity, whereas the significant capacity fading is caused by the low reversibility conversion reaction and volume expansion. In this work, we proposed a precipitation-polymerization-thermal treatment method to construct SnO 2 -based composites by precipitation reaction of SnCl 2 with moderately exfoliated graphite (MEG), subsequent dopamine (DA) polymerization and thermal treatment to fulfill nitrogen-doped-carbon (NC) coating and part transformation of SnO 2 to Sn. Finally, we can obtain the SnO 2 /Sn/MEG@NC composites for high-performance lithium-ion batteries (LIBs). The conductive NC coating and MEG matrix have the function in facilitating electron transportation, restraining aggregation, and adapting to volume change of SnO 2 /Sn particles. Micron-sized Sn is broken during the cycles and forms nano-sized distribution with ultrafine SnO 2 , the hybrid SnO 2 /Sn allows highly effective reversibility conversion and alloying/de-alloying reactions upon cycles. As a result, the SnO 2 /Sn/MEG@NC electrode exhibits outstanding cycling stability (837.2 mAh g−1 at 1 A g−1 after 800 cycles), displaying outstanding performance for being LIBs.
