Lithium‐ion batteries (LIBs) have gained widespread attention due to their numerous advantages, including high energy density, prolonged cycle life, and environmental friendliness. Nevertheless, their electrochemical performance deteriorates rapidly under extreme temperature conditions, accompanied by a series of safety issues. Electrolyte optimization has emerged as a crucial and feasible strategy to expand the operational temperature range of LIBs. This review comprehensively summarizes the challenges, advances, and characterization methodologies of electrolytes at both subzero and elevated temperatures. Initially, it discusses the degradation mechanisms of different types of electrolytes at extreme temperatures, integrates recent advances, and offers insights into future research directions. Subsequently, various experimental techniques are systematically presented to evaluate the fundamental physical properties, stability, and dynamic behaviors of electrolytes in non‐ambient environments. Finally, it also provides relevant computational methods across the electronic, molecular, and macroscopic scales, and explores the application of high‐throughput techniques in this field. This review offers valuable guidance for breaking the working temperature limits of electrolytes and promoting the development of next‐generation LIBs.

“…These effects include enhancing the SEI, suppressing lithium dendrite growth, reducing electrode polarization, and inhibiting shuttle effects [ 73 ]. A stable SEI was derived from a moderately concentrated electrolyte reported by Wang et al [ 74 ]. This inorganic SEI enriched with Li 2 O and LiF nanocrystals was able to promote the diffusion of Li + and exhibited a wide temperature range (− 40 ~ 60 °C) of applications.…”

Electrolyte design holds the greatest opportunity for the development of batteries that are capable of sub-zero temperature operation. To get the most energy storage out of the battery at low temperatures, improvements in electrolyte chemistry need to be coupled with optimized electrode materials and tailored electrolyte/electrode interphases. Herein, this review critically outlines electrolytes’ limiting factors, including reduced ionic conductivity, large de-solvation energy, sluggish charge transfer, and slow Li-ion transportation across the electrolyte/electrode interphases, which affect the low-temperature performance of Li-metal batteries. Detailed theoretical derivations that explain the explicit influence of temperature on battery performance are presented to deepen understanding. Emerging improvement strategies from the aspects of electrolyte design and electrolyte/electrode interphase engineering are summarized and rigorously compared. Perspectives on future research are proposed to guide the ongoing exploration for better low-temperature Li-metal batteries.

“…1,2 However, unwanted Li dendrite growth ascribed to a high diffusion barrier of Li, inhomogeneous electrical eld, and uneven Li-ion ux would break SEI and pierce the membrane, causing cell failure and even thermal runaway, leading to serious safety hazards. 3,4 Various strategies, such as building articial SEI layers with high mechanical modulus, good electrical insulation, and rapid Li-ion diffusion rate; 5,6 optimizing electrolytes, including introducing electrolyte additives and using high-concentration lithium salt electrolytes; 7,8 constructing 3D hosts with unique surface chemistry and interconnecting structures; 9,10 regulating surface lithiophilicity by introducing lithiophilic nucleation sites, have been employed to alleviate the growth of lithium dendrites. 11,12 Among these, regulating surface lithiophilicity can control Li + ux during plating, triggering uniform Li deposition and thus alleviating lithium dendrite growth.…”
