“…This might be due to the addition of FEC additive (5 wt%), consumed during the cycling process and helps achieve a stable electrode/electrolyte interface. 65–67 To optimize the amount of liquid electrolyte needed to improve the interface for the hybrid battery, we made three more cells with different amounts (5, 10, and 15 μL) of 1 M NaClO 4 in PC:FEC on the cathode side. The cells made with 5 and 10 μL of liquid electrolytes got short-circuited after 1st cycle, indicating insufficient wettability and poor interface.…”

Rechargeable batteries are highly in demand to power various electronic devices and future smart electric grid energy storage. The electrode–electrolyte interphases play a crucial role in influencing the electrochemical performance of batteries, with the solvation chemistries of the electrolyte being particularly significant in regulating these interfacial reactions. However, the reaction mechanisms of electrolyte solvation and their specific functions in batteries are not yet fully understood. In this review, we embark on an exploration of the fundamental principles governing solvation and present a comprehensive overview of how solvation structures impact interfacial reactions at the electrode–electrolyte interface. We underscore the significance of interactions among cations, anions, and solvents in shaping electrolyte solvation structures. The primary strategies for controlling solvation structures are also discussed, including the optimization of salt concentrations, solvent interactions, and the introduction of functional cosolvents. Furthermore, we elucidate the oxidation/reduction reaction mechanisms of electrolyte components in different solvation structures and the new understanding of electrolyte additives in modulating interfacial chemistries in batteries. Additionally, we emphasize the importance of incorporating new characterization techniques and theoretical simulations to attain a deeper understanding of the intricate processes taking place within batteries. This review provides an in‐depth understanding in solvations and interphasial properties and new ideas for designing advanced functional electrolytes for rechargeable batteries.

“…In detail, the electrolyte’s viscosity increases at low temperatures and even partial solidification, and the compatibility between the electrolyte and the cathode or the separator drops, leading to the Li + diffusion coefficient, and the ion conductivity decreases in the solvent. Also, the LIBs are always vulnerable to reduced discharge capacity and probably fail to operate. − …”

Adding lithium difluorophosphate into the original electrolyte results in outstanding eletrochemical performances among low temperatures, as documented in our earlier published work; therefore, to be able to gain more stability in lowtemperature performances, in this work, a kind of linear carboxylate cosolvent, EB (ethyl butyrate), is introduced, which has low viscosity (0.639 mPa s), high ion conductivity (5.18 mS cm −1 ), and ultralow melting point (−93 °C). The study's results show that the basic electrolyte's conductivity and viscosity are correspondingly 2.9 mS cm −1 and 3.34 mPa s at −40 °C; however, comparing under the same condition, after adding 16% EB into the baseline, the conductivity and viscosity are 3.37 mS cm −1 and 3.07 mPa s, whose amplitude changes show that the conductivity has increased by 16.2% and the viscosity has dropped by 8% in the interim. Therefore, the addition of EB can clearly boost conductivity, also drastically decreasing the electrolyte's viscosity, further to signify that the addition of EB can contribute to the decrease in the resistance during lithium-ion transport in cold conditions. Besides, the electrochemical properties of the batteries during cold conditions can be obviously improved by adding EB. In addition, after 50 cycles of −40 °C, the basic electrolyte has a discharge capacity of 81.94 mAh g −1 ; on the contrary, the cells using the 16 EB-modified coreagent maintains a discharge capacity of 112.3 mAh g −1 under the same conditions. Overall, the cells containing EB perform exceptionally well at low temperatures and are capable of meeting the appliance of Li-ion batteries in a cool environment.
