摘　　要：Lithium-selenium(Li-Se)batteries have attracted increasing attention as one of the next-generation battery systems due to much higher electronic conductivity and comparable volumetric capacity of Se compared to the popular sulfur cathode.However,its practical application still faces great challenges,especially the rapid capacity decay triggered by the loss of active Se species.A comprehensive review to uncover the in-depth failure mechanism and provide targeted solutions to promote the stable operation of Li-Se batteries is urgently needed.This review systematically summarizes the strategies in the new perspective,focusing on the optimization of Se utilization in Li-Se batteries by keeping a high Se maintenance in the cathode and accelerating the electrochemical kinetics of lithium polyselenides(LiPSe)conversion.On the basis of stru ctural design and Li_(2)Se active material introduction to accommodate volume expansion,blocking s huttle transport of LiPSe by physical/chemical adsorption,bonding Se with polymers or cathode electrolyte interphase(CEI)construction,and catalytic design to accelerate the conversion of LiPSe,different strategies for improving the utilization of Se have been evaluated and discussed.To address the inevitable loss of Se,prospects on inactive Se reactivation and Li protection are detailedly proposed and analyzed referring to the chemistry and corrosion science.Additionally,the perspectives on the future design and comprehensive parameter evaluations for the optimization of Li-Se batteries are recommended.This review comprehensively explains the causes and solutions of capacity fading and provides potential efforts for lifespan expansion of batteries,shedding light on the future development of Li-Se batteries.
