氧化亚硅用于锂离子电池负极材料的研究进展
Research Progress of Silicon Suboxide as Anode Materials for Lithium-Ion Batteries
摘要
Abstract
To address the urgent demand for high-energy-density of energy storage systems in electric vehicles and portable electronic devices,it is urgent to develop novel lithium-ion battery anode materials.Silicon suboxide(SiOx,0<x<2),with its high theoretical specific capacity and structural stability brought by the incorporation of oxygen,is regarded as a highly promising high capacity anode material.However,the practical application of SiOx still faces challenges such as large volume variation(160%~200%),low initial Coulombic efficiency,and poor electrical conductivity.This paper systematically reviews the structural models,lithium storage mechanisms,and modification strategies for SiOx,including nanostructure design,composite material design,and prelithiation techniques.These approaches effectively alleviate the volume expansion of SiOr,improve its conductivity and interfacial stability,and significantly enhance its initial Coulombic efficiency.Future efforts should focus on developing simple,scalable,and environmentally friendly preparation processes,aiming for high capacity and high initial Coulombic efficiency while comprehensively considering overall electrochemical performance,thereby promoting the practical application of SiOx as anode material in high-efficiency energy storage systems.关键词
