“…It helps maintain the cathode surface intact, protect transition-metal ions from dissolving, and prevent excessive electrolyte consumption during the charge and discharge process. [111][112][113][114] Regarding the components of the CEI film, some inorganic species such as LiF and Li x PF y O z are insoluble during the electrochemical process, [115] while Li 2 CO 3 [116] and some organic species like ROCOOLi [117,118] are believed freely soluble. Commercial additives such as 1,3-propyl sulfonolactone (PS) and Dioxathiolane 2,2-dioxide have been extensively used, however, their application is impeded by issues to thermal stability.…”

With the continuously growing demand for wide‐range applications, lithium‐ion batteries (LIBs) have been increasingly required to work under conditions that deviate from room temperature. However, commercial electrolytes exhibit low thermal stability at high temperatures and poor dynamic properties at low temperatures, hindering the operation of LIBs under extreme conditions. The bottleneck restricting the practical applications of LIBs has promoted researchers to pay more attention to developing a series of innovative electrolytes. This review primarily covers the design of electrolytes for LIBs from a temperature adaptability perspective. Firstly, we elaborate on the fundamentals of electrolytes concerning temperature, including donor number, dielectric constant, viscosity, conductivity, ionic transport, and theoretical calculations. Secondly, prototypical examples, such as lithium salts, solvent structures, additives, and interfacial layers in both liquid and solid electrolytes, are presented to explain how these factors can affect the electrochemical behavior of LIBs at high or low temperatures. Meanwhile, the principles and limitations of electrolyte design are discussed under the corresponding temperature conditions. Finally, a summary and outlook regarding electrolyte design to extend the temperature adaptability of LIBs are proposed.This article is protected by copyright. All rights reserved

Improving the wide‐temperature operation of rechargeable batteries is crucial for boosting the adoption of electric vehicles and further advancing their application scope in harsh environments like deep ocean and space probes. Herein, recent advances in electrolyte solvation chemistry are critically summarized, aiming to address the long‐standing challenge of notable energy diminution at sub‐zero temperatures and rapid capacity degradation at elevated temperatures (>45°C). This review provides an in‐depth analysis of the fundamental mechanisms governing the Li‐ion transport process, illustrating how these insights have been effectively harnessed to synergize with high‐capacity, high‐rate electrodes. Another critical part highlights the interplay between solvation chemistry and interfacial reactions, as well as the stability of the resultant interphases, particularly in batteries employing ultrahigh‐nickel layered oxides as cathodes and high‐capacity Li/Si materials as anodes. The detailed examination reveals how these factors are pivotal in mitigating the rapid capacity fade, thereby ensuring a long cycle life, superior rate capability, and consistent high‐/low‐temperature performance. In the latter part, a comprehensive summary of in situ/operational analysis is presented. This holistic approach, encompassing innovative electrolyte design, interphase regulation, and advanced characterization, offers a comprehensive roadmap for advancing battery technology in extreme environmental conditions.
