Summary: To solve the problem of capacity attenuation in SiO2 during charge and discharge, a rGO@yolk-shell SiO2 structure was designed using reduced graphene oxide as the conductive network and loading carbon-coated SiO2 as the yolk-shell structure. The yolk-shell structure effectively mitigates volume change without damaging the carbon layer, and the combination of rGO and the carbon layer enables efficient electron transport. As an anode material for lithium-ion batteries, rGO@yolk-shell SiO2 exhibits stable cycling performance with a capacity of 616 mAh g-1 after 358 cycles at 0.1 A g-1. (c) 2022 Elsevier B.V.

Summary: This study presents a novel strategy to increase the reversible capacity of electrode materials by altering the lithiation mechanism of transition metal oxides, exemplified by the conversion of MoO2 to CoMoO3. X-ray absorption spectroscopy and X-ray diffraction revealed the amorphization of the host structure due to the conversion of CoO to Co and Li2O. The high initial Coulombic efficiency of CoMoO3 is attributed to the highly conductive Co and MoO2, enhancing electronic conductivity.
