硅基负极体系从液态电解质到全固态电解质的转变:界面构效关系与调控策略OA

Following the central theme of"electrolyte regulation-interfacial evolution-performance enhance-ment",this review systematically summarizes the key challenges and recent progress of silicon-based anodes in liquid,quasi-solid-state,and all-solid-state electrolyte systems.Particular attention is paid to the synergistic effects of prelithiation,binder optimization,and electrolyte-formulation regulation in liquid electrolyte systems;the advantages of solid‒liquid cooperation in mitigating the volume expansion of silicon-based anodes in quasi-solid-state electrolyte systems from chemically dominated side reactions to dominated contact failure.The key strategies involving multiscale structural design,interfacial engineering,and cell-level synergistic optimization are summarized.The prospects for the commercial application of silicon-based anodes in high-energy-density battery systems are also discussed.This review provides a useful reference for understanding the interfacial structure‒property relationships and regulation mechanisms of silicon-based anodes under different electrolyte systems,and may also offer guidance for the development of other high-capacity anode materials.
