摘要：

Ternary SnO2-MoO2-GO (SMGO) nanocomposites were synthesized by hydrothermal method, modified Hummers method, and ball milling method. SMGO nanocomposites have the following advantages, including mitigating volume expansion during cycling, enhancing conductivity, and reducing the transmission path length for both electrons and Li+. Consequently, the SMGO composite material demonstrates a capacity of 1215.2 mAh/g after 200 cycles at 0.2 Ag-1, and a capacity of 1032.9 mAh/g after 1000 cycles at 1.0 Ag-1. Moreover, subsequent SEM analysis of the electrode material reveals the absence of accumulation or notable cracks, underscoring the remarkable cycling stability of the SMGO composite material.
