摘要：
Due to its high energy density, environmental friendly, and low cost, lithium-sulfur battery (LiSB) has attracted more and more attentions as a promising next-generation energy storage device. However, the insulation property, polysulfide shuttle effect, and the slow redox kinetics of the active Li2Sx material could lead to serious capacity attenuation, and further affect the cycle stability of the batteries. Therefore, the use of catalytic materials to accelerate the redox kinetics and hence to increase the performance and stability of LiSB has extensively developed. In this review, the catalytic transformation of sulfur-related compounds were discussed from the aspects of polysulfides generation, sulfur species transformation, and of lithium sulfides deposition. The state-of-the-art researches of catalytic materials for LiSB was reviewed, including the design strategies, the catalytic mechanisms, and the corresponding evaluation methods, so as to provide new ideas for high activity LiSB catalyst materials. © 2021, Chemical Industry Press Co., Ltd.
