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/SnO₂ nanorods, in which the SnO₂ 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/SnO₂. 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.

通过碳铆接策略提高石墨烯/ SnO2纳米棒的锂存储性能

石墨烯/金属氧化物（MO）纳米复合材料有望作为锂离子电池（LIB）的阳极应用。然而，在后续处理期间石墨烯的重堆积仍然是提高锂存储性能所要克服的挑战。本文报道了夹层结构碳铆接石墨烯/ SnO ₂纳米棒的制造，其中SnO ₂纳米棒被限制在石墨烯上的碳层形成的纳米空间中，通过两步水热处理，然后进行热处理。电化学测试表明，碳铆接的纳米层显着改善了石墨烯/ SnO ₂的锂存储性能。纳米复合材料显示出815 mAh g ^-1的高可逆容量在100 mA g ^-1下进行150次循环后，在1000 mA g ^-1下具有高循环稳定性。这项工作提供了一种有效的方法来为LIB操作具有改善性能的石墨烯/基于MO的纳米复合材料。
