摘要 :

Sulfur cathodes are inexpensive to produce and have several promising electrochemical characteristics, such as a high theoretical charge-storage capacity and active-material utilization. The advantages of sulfur cathodes benefit the pursuit of affordable, stable, and advanced lithium-ion batteries featuring a high energy density. However, despite these merits, there are barriers to a commercially viable method for producing lithium–sulfur batteries, hindering their rapid commercialization. One such barrier is that the intrinsic insulating nature of active solid-state materials and the fast and uncontrollable migration of active liquid-state materials cause a low electrochemical utilization and poor redox reversibility of sulfur, which derives challenges in electrode design and cell fabrication. Our group designs a novel method for the fabrication of metal–sulfur energy-storage materials for exploring the battery electrochemistry with high reaction kinetics and stability, and for optimizing the battery engineering with high amount of active material featuring high energy density.
