Enhancing the Lithium Storage Performance of Graphene/SnO 2 Nanorods by a Carbon‐Riveting Strategy

Graphene/metal oxide (MO) nanocomposites hold great promise for application as anodes in lithium‐ion batteries (LIBs). However, the restacking of graphene during subsequent processing remains a challenge to overcome for enhanced lithium storage properties. Herein, the fabrication of sandwich‐architecture carbon‐riveted graphene/SnO 2 nanorods, in which the SnO 2 nanorods are confined in the nanospaces formed by the carbon layers on graphene, by a two‐step hydrothermal process followed by thermal treatment, is reported. Electrochemical tests show that the carbon‐riveted nanolayers significantly improve the lithium storage performance of graphene/SnO 2 . The nanocomposite displays a high reversible capacity of 815 mAh g −1 after 150 cycles at 100 mA g −1 and high cycling stability at 1000 mA g −1 . This work provides an efficient way to manipulate graphene/MO‐based nanocomposites for LIBs with improved performance.
