摘　　要：Ionic liquids(ILs)have been deemed as promising electrolyte materials for building safer and highly-performing rechargeable lithium batteries,owing to their negligible volatility,low-flammability,and high thermal stability,etc.The profound structural designability of IL cations and anions allows relatively facile regulations of their key physical(e.g.,viscosities,and ionic conductivities)and electrochemical(e.g.,anodic,and cathodic stabilities)properties,and therefore fulfills the critical requirements stipulated by various battery configurations.In this review,a historical overview on the development of ILs for nonaqueous electrolytes is provided,and the correlations between chemical structures and the basic properties of ILs are discussed.Furthermore,the key achievements in the field of IL-based electrolytes are scrutinized,including liquid electrolytes,polymer electrolytes,and composite polymer electrolytes.Based on literature reports and our previous work in this field,possible strategies to improve the performance of IL-based electrolytes and their rechargeable batteries are discussed.The present work not only provides the status quo in the development of IL-based electrolytes but also inspires the structural design of ILs for other kinds of rechargeable batteries(e.g.,sodium,potassium,zinc batteries).
