“…Urea as one of the simplest and most-common organic compound is the H-bond acceptor and donor due to its carbonyl and amino groups, indicating its potential antifreeze characteristic (Figure 4i). [68][69][70] Qian et al developed the NaClO 4 -H 2 O-Urea electrolyte remained unfrozen under −40 °C when the molar ratio of NaClO 4 , H 2 O, and Urea was 1:2:2, because the bonding energy between water and urea molecules was stronger than that of water-water and it was favorable for inhibiting the formation of the regular H-bonds network among water molecules. [71] Equally intriguingly, the dissolution of electrodes can be efficiently prevented and the electrochemical stable window (ESW) of aqueous electrolyte can be expanded up to 3.3 V due to the reduced number of free water molecules when urea was introduced.…”

Therefore, it is increasingly urgent to develop novel unfrozen aqueous electrolytes to balance electrochemical performance and demand under lowtemperature. Hence, we comprehensively discuss the anti-freezing mechanisms and the composition of low-temperature electrolytes, as well as summarizing recently related reports in a timeline of milestones in the development process of low-temperature ARES (Figure 1a). Inspired by those reported works, how to modulate and optimize the component of aqueous electrolytes to remain unfrozen under ultralow temperature with ideal ionic conductivity is of particular importance to enlarge their application scope.As the ionic transport mediums, electrolytes play a crucial role in ionic migration between cathode and anode electrodes during the electrochemical processes, which are generally composed of appropriate salts and solvents. [12,13] Compared with most frequently-used organic solvents, the high solidification point (0 °C, 1 atm) of pure water as the main solvent for aqueous electrolytes primarily leads to inferior ion transfer under low temperature, restricting the broad application of ARES. [11,14] Thus, understanding the root cause of the abnormal freezing point for water among chalcogen hydrides is an essential precondition to develop lowtemperature aqueous electrolytes. The most apparent difference in various pure chalcogen hydrides is the unique existence of hydrogen bonds (H-bonds) in the pure water system. [15,16] H-bond is the essence of the coordinate bond between lonepair electrons in the strongly electronegativity N, O, or F atoms and hydrogen atom with partial positive charge rather than the shared electron pair effect (Figure 1b). From the chemical composition, the polar water molecules containing two atoms of hydrogen and one atom of oxygen in per chemical formula are H-bonds acceptors and donors at the same time, because the oxygen side with two lone-pair electrons has negative charge and the hydrogen side has positive charge, which provide the condition for H-bonds formation. Subsequently, the viscosity of liquid water increases and H-bonds restrict the vibration of water molecules, boosting the formation of longrange ordered crystalline structure under subzero temperature. Theoretically, one water molecule can effectively interact with up to four nearest neighbor water molecules by H-bonds interaction to generate the self-associated water clusters, which has the short-range ordering in the form of tetrahedral H-bonds within the water clusters due to the sp 3 hybridization of O Aqueous rechargeable energy storage (ARES) has received tremendous attention in recent years due to its intrinsic merits of low cost, high safety, and environmental friendliness. However, the relatively higher freezing point of conventional aqueous electrolytes results in sluggish kinetics and inferior ion transport efficiency under low temperature, severely restricting their further development and practical applications. In order to deal with the existing issues, the design principles ...

To meet the increasing desire for a means of powering wearable and portable devices, the development of high‐performance flexible aqueous rechargeable lithium‐ion batteries (FARLIBs) would be greatly desirable. The design of binder‐free cathode materials with 3D architectures is the key to develop FARLIBs. Herein, self‐standing 3D Ni‐doped LiMn2O4 (NLMO) nanosheets are successfully prepared assembled by nanowall arrays (NWAs) directly grown on carbon cloth (CC) as the cathode for LIBs, which is performed to slow down the dissolution of Mn and the Jahn–Teller effect of LiMn2O4 during the reaction process. The as‐prepared NLMO NWAs/CC electrode delivers a high capacity of 113.27 mAh g−1 at a current density of 1 A g−1, and can also have a capacity retention rate of 81% after 500 cycles at 10 A g−1, both higher than that of pure LiMn2O4. The results of density functional theory simulation demonstrate that the Ni‐doped LiMn2O4 can significantly decrease the bandgap and Li ions diffusion barriers. A quasi‐solid‐state FARLIB is successfully constructed by using NLMO NWAs/CC as the positive electrode and rugby‐shaped NaTi2(PO4)3/CC as the negative electrode, exhibiting remarkable electrochemical performance and flexibility. These results offer a new opportunity for developing high‐performance FARLIB.
