Aqueous metal-ion batteries are considered nextgeneration energy storage devices with improved safety. However, they suffer from sluggish kinetics and side reactions. This work presents a zinc-ion encapsulation strategy based on the poloxamer pre-solvation sheath for the realization of efficient zinc anode− electrolyte interfaces. The poloxamers can reversibly self-assemble into a pre-solvation sheath by electron-donating effect and effectively shield the ions from the surrounding water. This also lowers the activation energy of desolvation, endowing promoted transference and reaction kinetics. Accordingly, the Zn||Zn cell with the poloxamer electrolyte (Polo-ZnSO 4 ) achieved over 2000 h cycles at 5 mA cm −2 and even over 500 h cycles at 10 mA cm −2 . The Zn||MnO 2 battery delivers a high and stable capacity of 240.9 mAh g −1 after 1000 cycles at 1 A g −1 . This work paves the way for use of encapsulation chemistry for advanced aqueous metal batteries with high Coulombic efficiency and long lifetime.

“…They imply that the relative free energy of solvation energy is strongly correlated with zinc nucleation/dissolution kinetics and HER inhibition, exhibiting typical volcanic behavior (Figure 2d). 37 Zhang et al presented ovalbumin (OVA) as a multifunctional electrolyte additive for AZIBs. Experimental characterizations and theoretical calculations reveal that the OVA additive can replace the solvated sheath of recombinant hydrated Zn 2+ through the coordination water, preferentially adsorbed on the surface of the Zn anode.…”

The emerging aqueous zinc-ion batteries (AZIBs) are considered to be one of the promising candidates for large-scale energy storage systems due to their high theoretical capacity, low cost, and ecofriendliness. However, the instability of the zinc metal anode side seriously hinders the practical application of AZIBs. Recently, numerous researchers have focused on improving a series of problems related to the alignment of zinc anodes through electrolyte optimizations. In order to thoroughly and comprehensively understand the underlying mechanisms of these strategies, in this review, the origin of uneven Zn deposition/ dissolution and interfacial side reactions of zinc anodes in a mild electrolyte are discussed. Ulteriorly, the research progress and corresponding strategies for improving zinc anodes with electrolytes are summarized, including changing the structure of the solvation sheathing, adjusting the Zn deposition behavior, the in situ solid electrolyte interface protection mechanism, and the interfacial pH buffer. Furthermore, we discuss potential future research directions and key focus areas for overcoming the challenges that AZIBs may encounter in their path toward industrialization.

“…The high OH – concentration triggers the corrosion reaction of Zn metal to produce the inactive Zn 4 SO 4 (OH) 6 · x H 2 O byproducts that block ion and electron transportation. , In addition, the solvation effect of Zn 2+ ions with six water (H 2 O) molecules in aqueous electrolyte induce a high energy barrier for the desolvation of Zn 2+ before plating, which directly impacts Zn nuclei and deposition. , Therefore, inhibiting dendrite growth, reducing side reaction, and controlling solvation structure are all necessary for the improvement of electrochemical performance for Zn metal anodes and the implementation of commercialization for Zn batteries. Various strategies have been adopted to solve the above-mentioned issues and enhance electrochemical performance, including surface modification (Zn sulfur, polyvinyl butyral, lignin, tannin acid, and sodium titanate), electrolyte optimization (methanol, ethylene diamine tetraacetic acid and tetrasodium salt, , sucrose, monosodium glutamate, and boric acid), function membrane development (polyacrylonitrile, bamboo cellulose, and poly(vinyl alcohol)), and deposition carrier design (Cu nanowire networks, Zn micromesh, and Sn-modified carbon fibers).…”

The commercial application of high-safety aqueous zinc (Zn) secondary batteries is hindered by the poor cycling life of Zn metal anodes. Here we propose a dendrite growth and hydrogen evolution corrosion reaction mechanism from the binding energy of the deposited crystal plane on the Zn surface and the adsorption energy of H 2 O molecules on different crystal planes as well as the binding energy of H 2 O molecules with Zn 2+ ions. The biomass-based alkyl polyglucoside (APG) surfactant is adopted as an electrolyte additive of 0.15% to regulate the preferential growth of a parallel Zn(002) plane and enhance the anticorrosion ability of Zn metal anodes. The robust binding and adsorption energies of APG with Zn 2+ ions in the aqueous electrolyte and the Zn(002) plane on Zn surface generate a synergistic effect to increase the concentration of Zn 2+ ions on the APG-adsorbed Zn(002) plane, endowing the continuous growth of the preferential parallel Zn(002) plane and the excellent anticorrosion capacity. Accordingly, the long-term cycle stability of 4000 h can be achieved for Zn anodes with APG additives, which is better than that with pure ZnSO 4 electrolyte. With the addition of APG in the anolyte electrolyte, Zn-I 2 full cells display excellent cycling performance (70 mAh g −1 after 20000 cycles) as compared with that without APG additives.
