摘要

Abstract

Lithium-sulfur(Li-S)batteries have great promise for next-generation energy storage devices due to the high theoretical specific capacity(1675 mAh g-1)of sulfur with chemical conver-sion for charge storage.However,their practical use is hindered by the slow redox kinetics of sulfur and the"shuttle effect"arising from dissolved lithium polysulfides(LiPSs).In recent years,vari-ous carbon-based materials have served as sulfur hosts and cata-lysts for accelerating sulfur conversion redox kinetics and alleviat-ing LiPS shuttling.However,they often suffer from irreversible passivation and structural changes that destroy their long-term performance.We consider the main problems limiting their stabil-ity,including excessive LiPS adsorption,passivation by insulat-ing Li2S,and surface reconstruction,and clarify how these factors lead to capacity fade.We then outline effective strategies for achieving long-term sulfur catalysis,focusing on functional car-bon,such as designing suitable carbon-supported catalyst inter-faces,creating well-distributed active sites,adding cocatalysts to improve electron transfer,and using carbon-based protective layers to suppress unwanted side reactions.Using this information should enable the development of stable,high-activity catalysts capable of long-term operation under practical conditions in Li-S batteries.
