金属锂负极溶剂化结构调控的研究进展

Owing to the extremely high theoretical specific capacity and low electrode potential，lithium（Li）metal anode is regarded as the ultimate anode option for next-generation secondary batteries. However，the unstable electrode/electrolyte interface results in massive lithium dendrite during cycling，giving rise to a rapid capacity loss and a severe safety problem. Regulating the solvation structure of Li ions and therefore promoting the preferential decomposition of beneficial solid electrolyte interphase（SEI）film-forming components on Li metal surface is an imperative outlet to enable uniform Li deposition，which is strongly considered when designing liquid and quasi solid-state electrolyte for Li metal batteries. In this review，the typical strategies and design principles for regulating the solvation structure of Li ions in liquid and quasi solid-state electrolytes are summarized. Deep insights are afforded into the correlation between Li ion solvation structures and the resulting electrochemical properties. Critical perspectives on the future research in this field are further pointed out.
