Free-standing SnO2 nanoparticles@graphene hybrid paper for advanced lithium-ion batteries

A free-standing SnO2/reduced graphene oxide (re-G) hybrid paper has been successfully fabricated by a facile vacuum filtration approach through a uniformly dispersed SnO2 nanoparticle and graphene oxide mixed solution. As potential anode material for high power and energy applications, the hybrid nanostructures were directly evaluated as anode for rechargeable lithium ion batteries without adding any polymer binder, conductive additives or current collectors. And the composite exhibits a greatly enhanced synergic effect with extremely high energy storage stability of 700 mAh g−1 after 100 cycles benefiting from the advanced structural features.
