Summary: This work proposes a facile covalent self-assemble strategy to prepare the ZrN@rGO composite for enhanced LIB. The results show that a strong Zr-C covalent bond is formed between ZrN and rGO, and electron transfer promotes charge density at the ZrN@rGO heterointerface. The volume change of ZrN can be effectively alleviated by coupling with rGO, leading to a high specific capacity in the lithium-ion battery.

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.
