“…Therefore, the rst choice of lithium iron phosphate cathode material was more suitable for storing lithium ions. In previous studies on lithium-ion battery half-cells, the platform voltages of lithium in sodium vanadium phosphate and lithium iron phosphate were approximately 3.6 V and 3.4 V, respectively, with a difference of 0.2 V 29,30,31 . When we replaced the lithium metal in this battery system with an aluminum negative electrode, the standard hydrogen electrode potential of aluminum and lithium were − 1.66 and − 3.04 V vs SHE, respectively.…”

With the rapid development and increase in popularity of electric vehicles and wearable devices, battery safety in the field of energy storage has become an increasingly strong focus. Aluminum-ion batteries (AIBs) are gaining attention as energy-storage systems that are low cost with high levels of safety and high theoretical energy density. However, to date, the dense alumina passivation layer on the aluminum anode surface and the slow kinetic performance of the IL (ionic liquid) electrolyte has rendered their performance unsatisfactory. We have reported on a new type of lithium–aluminum battery that maintains a certain discharge performance under destructive conditions such as continuous bending, high- and low-temperature environments, and shearing. The prepared AlLi metal battery achieved a stable cycle of 130 mAh g− 1 specific capacity and approximately 260 Wh kg− 1 energy density at a wide voltage platform of 2 V and a test temperature of 25°C. The batteries did not experience combustion and this product can meet the current demand for flexible and safe batteries. We also analyzed the reaction mechanism and principle of this Al–Li cell based on density functional theory and conducted ex situ XRD and XPS tests to elucidate the storage mechanisms of the Al-Li battery.

“…However, it can be seen from Figure h,i that the improvement in the low-temperature performance of cells is still relatively limited. In addition, comparison of the low-temperature performance of LFMP with some similar materials described in the literature is listed in Table − It can be found that the low-temperature performance of the prepared LFMP@B/P–C material is poorer than other similar materials, thereby it needs to further improve the low-temperature performance of LFMP in the future. Furthermore, the too low temperature could cause the solidification of solvents such as ethylene carbonate in the electrolyte, which hinders the diffusion of lithium ions and increases the impedance of the cells.…”

Although LiMPO4 (M = Fe, Mn) cathode materials have been widely applied in electric vehicles owing to the advantages of excellent safety, cycle stability, and low cost, poor electronic conductivity of LiMPO4 severely limits the further expansion of its applied field. Herein, the LiFe0.8Mn0.2PO4 composite with boron/phosphorus dual-doped carbon coating (LFMP@B/P–C) was fabricated by a sol–gel hydrothermal method. As a result, LFMP@B/P–C exhibits superior rate performance (97.1 mAh g–1 at 20 C) and preferable low-temperature performance (78.2 mAh g–1 at 1 C and −20 °C). It is mainly attributed to the synergistic effect of boron/phosphorus dual-doped carbon coatings, as confirmed by combined experimental characterizations with density functional theory calculations. That is, boron-doped carbon coating offers additional hole carriers, and phosphorus doping provides abundant electron carriers, making it easy for electrons to escape and enter and greatly improving the conductivity of the material. In addition, the phosphorus atom also acts as a bridge so that the carbon coating layer is tightly coated on the surface of the material. This will provide an idea for the research on the modification of cathode materials in the future.

“…Nonaqueous lithium‐ion batteries (LIBs) have been dominating the portable electronics and electric/hybrid vehicles market due to their high energy density and long cycle life, [ 1–5 ] but the limitation of lithium resources, high‐cost, and safety issue, [ 3,4,6–10 ] hinder their further development for larger‐scale energy storage applications. Nonaqueous sodium‐ion batteries (SIBs) and potassium‐ion batteries (KIBs) use relatively abundant and low‐cost sodium and potassium elements, have become alternatives to LIBs.…”

future is not such bright. Therefore, the drawbacks of these organic-based batteries systems motivate us to explore the alternative battery with low-cost, high safety, and long-cycle-life. [20][21][22][23] Compared to nonaqueous batteries, aqueous batteries have the advantages of low cost, better safety, high ionic conductivity, easy processing, low manufacturing cost, etc., so that they are in a better position for large-scale energy storage applications. [24][25][26][27][28] Among them, the aqueous ZIBs have attracted tremendous attention due to their distinct advantages, that is, high gravimetric and volumetric capacity (820 mAh g −1 , 5855 mAh cm −3 ) offered by Zn metal, low redox potential of zinc (−0.763 V vs a standard hydrogen electrode), good stability of zinc metal in water compared to the extremely active lithium, sodium and potassium metals, as well as its highlighted low cost and natural abundance. [3,[29][30][31][32][33][34][35][36][37][38][39][40][41][42][43][44][45] Nevertheless, aqueous ZIBs still face several challenges that hinder their wider utilization: i) the dissolution of cathode materials and obstacles of intercalating into the host materials; [29,30] ii) the irreversible Zn stripping/plating process caused by formation of Zn dendrites and corrosion on the anode; [31,34,35,37,46] iii) the narrow electrochemical window in aqueous electrolyte; [30,33,36] iv) sluggish transport and solvation/desolvation of Zn 2+ . [15,36] All of them impact the capacity, life cycle, and rate property of aqueous ZIBs.Aqueous zinc ion batteries (ZIBs) are regarded as one of the most ideally suited candidates for large-scale energy storage applications owning to their obvious advantages, that is, low cost, high safety, high ionic conductivity, abundant raw material resources, and eco-friendliness. Much effort has been devoted to the exploration of cathode materials design, cathode storage mechanisms, anode protection as well as failure mechanisms, while inadequate attentions are paid on the performance enhancement through modifying the electrolyte salts and additives. Herein, to fulfill a comprehensive aqueous ZIBs research database, a range of recently published electrolyte salts and additives research is reviewed and discussed. Furthermore, the remaining challenges and future directions of electrolytes in aqueous ZIBs are also suggested, which can provide insights to push ZIBs' commercialization.The ORCID identification number(s) for the author(s) of this article can be found under https://doi.org/10.1002/smll.202104640.
