▎ 摘  要

A continuous gas-phase approach has been developed to prepare tin oxide (SnOx)-reduced graphene oxide (rGO) hybrid nanoflakes via a single-pass process. According to the TEM analysis, the SnOx particles are only distributed on the rGO particles from the gas-phase process. The hybrid particles obtained have a theoretical capacity of 774 mA h g(-1), and after 50 cycles the charge capacity of the hybrid particles still remained at 671 mA h g(-1), that is, with 86.7% retention of the reversible capacity. The dimensional confinement of the SnOx particles by the surrounding rGO limits the volume expansion upon lithium insertion, and the pores between the SnOx and rGO could be used as buffered spaces during charge-discharge, resulting in superior cyclic performances.
