摘要
Higb-energy-density lhiumslu(Li-S)bttries are drawing dramatic research interests to fulill the ever-increasing demands of etrical vehicles.However,chllenges with the insulating poperty of sulfur and its lihistion products aund its large volume expansion,aund the sutle eflet of lthiumn polysulides,hinder the commer-cial application of Li-S butteries.Lots of material design concepts have bocn developed to address the failure modes.Among them,bollw micro-/anostructures with abundant compositional und geometrical feasibility have been prored fuitful in adresing the cureut obstacles of LiS bttries Here,lypical examples of designing hollw mi-co-/anostructures to address the problemns of Li-S bttries and sinultuneously improve the practical capacity and lifespan are highlightedl.In purticular,the great efeet of structural engineering on minimizing volume change,inhi-biting the shutle efiet and catalyzing plysulide conversion are disussed systeatically. Fially fuure dreetions of hollow nanostrucure design to enhance the progress of Li-S butteries are also provided.
