摘要

Layered materials are promising as cathodes for aqueous zinc-ion batteries (AZIBs) due to the reduced complexity of 2D Zn2+ transport channels. Nevertheless, their weak cycle stability or limited capacity restricts their practical usage. We attempted to evolve a SnS2 cathode synthesized by a simple hydrothermal procedure for 0.86 nm-spaced ZIBs for the first time. We precisely monitored the Na ion insertion and extraction in a layered structure of SnS2 dominated by van der Waals interactions, leading to considerably high interspace layers SnS2 (SnS2-HIL) from 0.86 to 1.10 nm. It enables higher Zn2+ storage capacity in SnS2-HIL cathodes. The SnS2-HIL has an exceptionally high-rate performance and stable cycling over time, with 359 mA h g−1 at 0.1 A g−1 and 174 mA h g−1 at 10 A g−1, along with 83.7% of capacity maintained after 1000 cycles. Electrochemical investigations indicated improved Zn2+ migration kinetics and excellent pseudocapacitive behaviors. An ex situ study showed that a reversible phase change between Sn2+ and Sn4+ occurred after an energy-storing mechanism brought about by Zn ion insertion/extraction. This study opens up an exciting new opportunity for developing and optimizing 2D materials as high-performance cathodes for 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
