title: Unique interconnected graphene/SnO2nanoparticle spherical multilayers for lithium-ion battery applications.
abstract: We have designed and synthesized a unique structured graphene/SnO2composite, where SnO2nanoparticles are inserted in between interconnected graphene sheets which form hollow spherical multilayers. The hollow spherical multilayered structure provides much flexibility to accommodate the configuration and volume changes of SnO2in the material. When it is used as an anode material for lithium-ion batteries, such a novel nanostructure can not only provide a stable conductive matrix and suppress the mechanical stress, but also eliminate the need of any binders for constructing electrodes. Electrochemical tests show that the unique graphene/SnO2composite electrode as designed could exhibit a large reversible capacity over 1000 mA h g-1and long cycling life with 88% retention after 100 cycles. These results indicate the great potential of the composite for being used as a high performance anode material for lithium-ion batteries.
