要旨

Uncontrollable side reactions and dendrites severely undermine the stability and reversibility of Zn anodes and remain significant challenges for aqueous zinc-ion batteries (AZIBs). Herein, it is demonstrated that glutamine (Gln) is a multifunctional electrolyte additive to enable highly stable and reversible Zn anodes. Theoretical and experimental results reveal that Gln has three functions: preferentially absorbing on the Zn anode and constructing a water-poor interface, enhancing the steric effect, and optimizing the solvation structures of Zn2+. Consequently, Zn//Zn batteries exhibited an impressive cycling durability and high cumulative capacity at 3 mA cm−2. Furthermore, Zn//Cu batteries also demonstrated a remarkably reversible stripping/deposition process accompanied by a notably high average coulombic efficiency of 99.6%. In addition, the fabricated Zn//NH4V4O10 batteries with Gln also yielded impressive cycle performances and capacity retention. Gln exhibits promising attributes as a cost-effective and versatile electrolyte additive to facilitate the stability and reversibility of AZIBs.

Journal of Materials Chemistry A, B & C cover high quality studies across all fields of materials chemistry. The journals focus on those theoretical or experimental studies that report new understanding, applications, properties and synthesis of materials. The journals have a strong history of publishing quality reports of interest to interdisciplinary communities and providing an efficient and rigorous service through peer review and publication. The journals are led by an international team of Editors-in-Chief and Associate Editors who are all active researchers in their fields. Journal of Materials Chemistry A, B & C are separated by the intended application of the material studied. Broadly, applications in energy and sustainability are of interest to Journal of Materials Chemistry A, applications in biology and medicine are of interest to Journal of Materials Chemistry B, and applications in optical, magnetic and electronic devices are of interest to Journal of Materials Chemistry C. More than one Journal of Materials Chemistry journal may be suitable for certain fields and researchers are encouraged to submit their paper to the journal that they feel best fits for their particular article. Example topic areas within the scope of Journal of Materials Chemistry A are listed below. This list is neither exhaustive nor exclusive. Artificial photosynthesis Batteries Carbon dioxide conversion Catalysis Fuel cells Gas capture/separation/storage Green/sustainable materials Hydrogen generation Hydrogen storage Photocatalysis Photovoltaics Self-cleaning materials Self-healing materials Sensors Supercapacitors Thermoelectrics Water splitting Water treatment
