“…In addition to regulating the content of traditional carbonate solvents, various organic solvents such as carboxylate esters, [38] sulfite esters, [39][40][41] ethers, [42] and nitriles [43][44][45] have been employed as solvents in wide-temperature electrolytes. Zhao et al [41] chose dimethyl sulfite (DMS) as the sole solvent, characterized by an extremely low freezing point (À 141 °C) and a high dielectric constant (22.5), thereby balancing fast Li + conduction and sufficient Li + desolvation (Figure 3a).…”

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.

“…According to previous reports, the composition of the electrolyte has a significant effect on lithium electroplating [18][19][20]. Therefore, it is of great significance for the development and popularization of low-temperature lithium metal batteries to design new high-performance low-temperature electrolytes which is more conducive to promoting the uniform deposition/dissolution of lithium metal, inducing stable SEI and inhibiting dendrite growth [21][22][23]. Carbonate solvents, such as dimethyl carbonate (DMC) and vinyl carbonate (EC), have been widely used in the solvent system of LIBs organic electrolyte due to their advantages of high chemical stability and dielectric constant [24].…”

Low temperature has been a major challenge for lithium-ion batteries to maintain satisfied electrochemical performance, as it leads to poor rechargeability and low capacity retention. Commercial electrolytes of lithium-ion battery rely heavily on ethylene carbonate (EC), and its high melting point (36.4 °C) severely limits the use of batteries below 0 °C. In this work, we demonstrate that using the low melting point carboxylate of methyl propionate (MP) and vinyl fluorocarbonate (FEC) based electrolyte can overcome the low-temperature cycle limitation. Compared with carbonate electrolytes, MP has lower binding energy with Li+, which is essential to improve the low-temperature performance of the battery, and FEC is an effective component to inhibit the side reaction with the electrode of lithium metal. The carefully formulated MP-based electrolyte can generate a solid electrolyte interface with low resistance and rich in inorganic substances, which is conducive to the smooth diffusion of Li+, allowing the battery to successfully cycle at a high rate of 0.5 C at -20 °C, and giving it a reversible capacity retention rate of 65.3% at -40 °C. This work designs a promising advanced electrolyte and holds the potential to overcome limitations of lithium-ion batteries in harsh conditions.

Operating a lithium‐ion battery (LIB) in a wide temperature range is essential for ensuring a stable electricity supply amidst fluctuating temperatures caused by climate or terrain changes. Electrolyte plays a pivotal role in determining the temperature durability of batteries. However, specialized electrolytes designed for either low or high temperatures typically possess distinct features. Therefore, wide‐temperature electrolytes (WTEs) are necessary as they encompass a combination of diverse properties, which complicates the clear instruction of WTE design. Here we represent an artificial intelligence (Al)‐assisted workflow of WTE design through stepwise parameterizations and calculations. Linear mono‐nitriles are identified as ideal wide‐liquidus‐range solvents that can “softly” solvate lithium ions by weak interactions. In addition, the explainable modules revealed the halogenoid similarity of cyanide as fluorine on the electrolyte properties (e.g. boiling point and dielectric constant). With the further introduction of an ether bond, 3‐methoxypropionitrile (MPN) has been eventually determined as a main electrolyte solvent, enabling the battery operation from −60 to 120°C. Particularly, a LiCoO2/Li cell using the proposed WTE can realize stable cycling with capacity retention reaching 72.3% after 50 cycles under a high temperature of 100°C.
