Integration of permselective membranes – as a subset of the separator systems – in the configuration of lithium–sulfur battery, is a relatively simple solution to tackle the issue of polysulfide dissolution into the electrolyte. Cation-selective materials such as graphene oxide (GO) and Nafion have demonstrated to serve effectively as electrostatic shields for polysulfide anions, retarding their diffusion to the anode side of the battery. Looking into the future, the introducing of these materials in the configuration/composition of multifunctional/multilayered separator systems will promote the high efficiency cycling of high content sulfur cathodes. Enhanced performance metrics and careful minimisation of the mass/volume of these extra components should result in enhanced volumetric/gravimetric energy densities on a cell level for lithium–sulfur battery.

在锂硫电池的配置中，作为隔膜系统的子集的全选择性膜的集成是解决多硫化物溶解到电解质中的相对简单的解决方案。阳离子选择性材料（例如氧化石墨烯（GO）和Nafion）已证明可有效用作多硫化物阴离子的静电屏蔽，从而阻止其扩散到电池的阳极侧。展望未来，在多功能/多层隔板系统的结构/组成中引入这些材料将促进高含量硫阴极的高效循环。
