锂离子电池硅基负极醚类电解液研究进展OA

Lithium-ion batteries have become an important part of the energy storage systems in all aspects of modern life.With the continuous development of the economy and society,a new generation of high energy density lithium-ion batteries is highly anticipated.Silicon-based anodes have attracted much attention because of their high energy density and abundant natural reserves.However,the severe volume expansion and unstable electrode/electrolyte interface of silicon-based anodes have led to poor safety and unsatisfactory cycling stability,which has seriously hindered their commercial application.In recent years,ether electrolytes have been widely studied in high-performance lithium-ion batteries,and a common strategy is to enhance the performance of silicon-based anodes by constructing a stable interface through ether electrolyte systems.Therefore,this paper provides a comprehensive overview of the component design requirements of ether electrolytes,including lithium salts,additives,and solvents,the mechanisms of linear ethers and cyclic ethers,as well as the research results of ether electrolyte systems in improving the anode interfacial stability and cycling stability.Finally,an outlook on the design strategies and challenges of new ether electrolytes is provided.
