“…From the SEM images (Figure S9A,B,D,E,G,H), it could be seen that all three EC samples showed different degrees of cracks and detachment on the electrode surface after 1500 cycles, while the sample particles were fragmented. This may be induced by the large internal stress generated during cycling . Meanwhile, the EC600 has a higher surface integrity compared to those of the other two samples, coinciding with higher stability.…”

In addition, the interlayer spacing of the EC samples widened after cycling (Figure S9C,F,I), which could be attributed to the structure rebuilding induced by the sodium intercalation process.…”

Rechargeable sodium-ion batteries (SIBs) have been considered as promising energy storage devices owing to the similar "rocking chair" working mechanism as lithium-ion batteries and abundant and low-cost sodium resource. However, the large ionic radius of the Na-ion (1.07 Å) brings a key scientific challenge, restricting the development of electrode materials for SIBs, and the infeasibility of graphite and silicon in reversible Na-ion storage further promotes the investigation of advanced anode materials. Currently, the key issues facing anode materials include sluggish electrochemical kinetics and a large volume expansion. Despite these challenges, substantial conceptual and experimental progress has been made in the past. Herein, we present a brief review of the recent development of intercalation, conversion, alloying, conversion-alloying, and organic anode materials for SIBs. Starting from the historical research progress of anode electrodes, the detailed Na-ion storage mechanism is analyzed. Various optimization strategies to improve the electrochemical properties of anodes are summarized, including phase state adjustment, defect introduction, molecular engineering, nanostructure design, composite construction, heterostructure synthesis, and heteroatom doping. Furthermore, the associated merits and drawbacks of each class of material are outlined, and the challenges and possible future directions for high-performance anode materials are discussed.

“…However, crystalline materials are confronted with the following inevitable challenges due to their dense lattice structure, such as the sluggish reaction kinetics of ionic insertion/extraction and structure collapse during long-term cycling tests. [144][145][146][147] In addition, the desolvation rate of hydrated ion at the electrolyte/ electrode interphase severely decreases under low temperature. On this basis, amorphous materials without lattice restrictions possess isotropic feature, controllable structure, and abundant active sites for charge exchange, conducive to ionic transportation and storage.…”

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 ...
