外文摘要：Silicon(Si)is considered as one of the most promising anode materials for advanced lithium-ion batter-ies due to its high theoretical capacity,environmental friendliness,and widespread availability.However,great challenges such as volumetric expansion,limited ionic/electronic conductivity properties and com-plex manufacturing processes hinder its practical applications.Herein,a novel plasma-enhanced reduced graphene oxide fibers/Si(PrGOFs/Si)composite anode is first proposed by using wet-spinning technology followed by plasma-enhanced reduction method.The PrGOFs provide large space to accommodate the volume expansion of Si nanoparticles(SiNPs)by forming a flexible 3D conductive network.Compared to the conventional thermally reduced graphene oxide fibers/Si(TrGOFs/Si)sample,the PrGOFs/Si anodes demonstrate higher conductivity,specific surface area,and superior fabrication efficiency.Accordingly,the PrGOFs/Si anodes exhibit a reversible capacity of 698.3 mAh/g,and maintain a specific capacity of 602.5 mAh/g at a current density of 200mA/g after 100 cycles,superior to conventional TrGOFs/Si counter-parts.This research presents a novel strategy for the preparation of high-performance Si/carbon anodes for energy storage applications.
