要旨

In the rapidly advancing landscape of portable electronic devices, lithium–sulfur batteries (LSBs) have risen to prominence as a viable successor to traditional lithium-ion batteries. This review delves into the potential of Li2S, showcasing it as an exemplary cathode with high energy density, safety, and efficiency for LSBs. However, these promising facets are shadowed by notable impediments to its practical deployment, including constraints like inadequate electronic and ionic conductivity, an elevated initial activation overpotential, and the vexing challenge posed by the shuttle effect. The review systematically explores various strategies for overcoming these hindrances, with a concentrated focus on the engineering of Li2S, host materials and additives. While existing literature has addressed Li2S cathode technology to some extent, this review goes a step further by meticulously examining neglected aspects like polycrystalline Li2S and artificial cathode electrolyte interfaces. Through a deep analysis of the redox process of the Li2S cathode and by integrating diverse engineering strategies into three coherent areas, the review serves as a comprehensive guide that illuminates new insights and charts future pathways in the pursuit of high-performance LSBs utilizing Li2S cathode materials.

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
