Lithium sulfur batteries attract great attention due to their high energy density,while the real applications are still hindered by the rapid capacity degradation.Despite great effort devoted to solving the polysulfide shuttle between the cathode and anode electrodes,it remains as a serious challenge to build high-stable lithium sulfur battery,which related to the diffusion and reaction between polysulfides and the metal lithium anode.In this series of works,we proposed a strategy of introducing an ion selective membrane to improve the stability and coulombic efficiency of lithium sulfur battery.
