“…Increasing the concentration of salts is an efficient way to decrease the freezing point of a solution. The interaction between ions and water molecules enlarges the distance between water molecules and reduces the number of HBs between water molecules, effectively lowering the freezing point ( 31 ).…”

As one of the most competitive candidates for the next-generation energy storage systems, the emerging rechargeable zinc metal battery (ZMB) is inevitably influenced by beyond-room-temperature conditions, resulting in inferior performances. Although much attention has been paid to evaluating the performance of ZMBs under extreme temperatures in recent years, most academic electrolyte research has not provided adequate information about physical properties or practical testing protocols of their electrolytes, making it difficult to assess their true performance. The growing interest in ZMBs is calling for in-depth research on electrolyte behavior under harsh practical conditions, which has not been systematically reviewed yet. Hence, in this review, we first showcase the fundamentals behind the failure of ZMBs in terms of temperature influence and then present a comprehensive understanding of the current electrolyte strategies to improve battery performance at harsh temperatures. Last, we offer perspectives on the advance of ZMB electrolytes toward industrial application.

“…When the ambient temperature is near to the freezing point, carrier ions hardly migrate rapidly in the particularly high-viscosity aqueous electrolyte, which extremely causes sluggish electrochemical reaction kinetics and unsatisfactory low-temperature performance. [26,27] Therefore, decreasing the freezing point of electrolyte is an effective strategy to improve low-temperature electrochemical performance of ASIBs. According to the phase diagram of CaCl 2 solution (Figure S1, Supporting Information), when the content of CaCl 2 is ≈30 wt% (3.86 m), the calcium chloride solution possesses the lowest solidification temperature, which is why the CaCl 2 concentration used in this work is 3.86 m. [28] The light microscopes images of the optimized electrolyte are shown in Figure 1b and no obvious ice crystals from −40 to −100 °C during cooling process was observed.…”

Aqueous sodium ion batteries have received widespread attention due to their great application potential and high safety. However, the serious capacity fading under low temperature dramatically restricts their practical application. Compared to flammable and toxic organic antifreezing additives, addition of common cheap inorganic inert additives to improve low‐temperature performance is of interest scientifically. Herein, low‐cost calcium chloride is served as antifreezing additive in 1 m NaClO4 aqueous electrolyte due to its strong interaction with water molecules. The freezing point of the optimized electrolyte is significantly reduced to below −50 °C with an ultrahigh ionic conductivity (7.13 mS cm−1) at −50 °C. All pure inorganic composition of the full battery delivers a high capacity of 74.5 mAh g−1 under 1 C (1 C = 150 mA g−1) at −30 °C. More importantly, when tested under 10 C at −30 °C, the battery can achieve an ultralong cycling stability of 6000 cycles with no obvious capacity decay, indicating fast Na+ transport under low temperature. Significantly, this work provides an easy‐to‐operate strategy by adding cheap inorganic salt to develop high‐performance low‐temperature aqueous batteries.

“…To tackle this problem, numerous articles concerning various strategies of modifying aqueous electrolytes have been published already to extend the low-temperature operational range of ARBs. [184][185][186][187][188][189][190][191][192][193] In the following section, several of these effective strategies to build smart ARBs with the capability to resist low temperature will be described in detail.…”

safe, environmentally friendly, and costefficient energy storage technologies. Since renewable and green energy sources such as solar, wind, and tide are available only intermittently, batteries are an exceptionally promising technology to store electricity generated from such sources for later use at the peak consumption times in large scale networks. [1][2][3][4] Commercial lithium-ion batteries (LIBs) with high energy density, cycle stability, and energy efficiency have dominated the energy storage field, and they provide a great convenience for our modern lives. [5,6] However, their further applications are hindered by safety concerns involving the use of harmful organic electrolytes and by the high cost of the appropriate electrode materials. [7,8] Lately, abundant sodium and potassium resources in nature have attracted much attention because of their similar chemical properties to lithium, where sodium-ion batteries and potassium-ion batteries have, thus, become promising alternatives for LIBs. [9][10][11][12] Although the issue of high cost can be solved using such novel battery materials, the usage of conventional organic electrolytes that are toxic and flammable still affects the safety of battery operation.
