【摘要】Owing to their low cost,high energy densities,and superior performance compared with that of Li-ion batteries,Li–S batteries have been

recognized

as

very

promising

next-generation

batteries.However,the commercialization of Li–S batteries has been hindered

by

the

insulation

of

sulfur,significant

volume

expansion,shuttling of dissolved lithium polysulfides(Li PSs),and more importantly,sluggish

conversion

of

polysulfide

intermediates.To

overcome these problems,a state-of-the-art strategy is to use sulfur host materials that feature chemical adsorption and electrocatalytic capabilities for Li PS species.In this review,we comprehensively illustrate the latest progress on the rational design and controllable fabrication of materials with chemical adsorbing and binding capabilities for Li PSs and electrocatalytic activities that allow them to accelerate the conversion of Li PSs for Li–S batteries.Moreover,the current essential challenges encountered

when

designing

these

materials

are

summarized,and possible solutions are proposed.We hope that this review could provide some strategies and theoretical guidance for

developing novel chemical anchoring and electrocatalytic materials for high-performance Li–S batteries. 【总页数】25页(P.144-168)
