要旨

Aqueous zinc-ion batteries (AZIBs) have been considered next-generation promising high-energy storage systems due to their cost-effectiveness and high safety. Nevertheless, the instability of the Zn metal anode posed by dendrite growth and volume changes presents a significant hurdle for AZIB commercialization. Here, we introduce a novel approach using a ZnIn2S4 nanoflower-coated carbon cloth (ZISG-CC) with hierarchical spatial channels to guide the nucleation and deposition of Zn, thereby constructing a stable Zn metal anode. The designed ZISG-CC electrode exhibits distinctive features, including an enlarged surface area, enhanced zincophilicity, and in situ formation of a ZnS/In interphase during the initial discharge process. These characteristics facilitate uniform Zn nucleation and the formation of a stable electrolyte–anode interface, enabling excellent reversibility of the Zn anode. As a result, the Zn/ZISG-CC anode demonstrates outstanding charge–discharge cycling performance in a symmetric cell, achieving 550 cycles at 10 mA cm−2/5 mA h cm−2 and 500 cycles at 20 mA cm−2/10 mA h cm−2. Furthermore, the Zn/ZISG-CC|MnO2-graphene full cell exhibits a high capacity retention of 87.5% after 1000 cycles at 1 A g−1, along with favorable flexibility. This study introduces a novel strategy that utilizes the interaction between the electrode and electrolyte to stabilize the electrolyte–anode interface, enabling advanced Zn anodes in high-performance 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
