摘要
锂硫电池因其具有较高的理论比容量和高能量密度被誉为下一代动力电池的最佳候选之一。引起研究者们的广泛关注,成为新型锂电池研究热点。隔膜作为电池的重要组成部分,起到解决多硫化锂穿梭效应和抑制锂枝晶的作用,是提升电池各方面性能的关键。商业膜因其具有良好的机械性能和适用于连续生产以及较低的成本,目前现阶段对隔膜的研究主要集中在对商业隔膜Celgard系列的改性方面。本文主要从改性隔膜涂层的种类和作用机理方面综述了锂硫电池隔膜改性的最新研究现状。
lithium-sulfur battery is regarded as one of the best candidates for the next generation power battery due to its high theoretical specific capacity and high energy density.It has attracted extensive attention from researchers and become a hot spot in the research of new lithium batteries.As an important part of battery,separator plays a role in solving the shuttle effect of lithium polysulfide and inhibiting lithium dendrite,which is the key to improving the performance of battery in all aspects.Due to its good mechanical properties,continuous production and low cost,the current research on separator mainly focuses on the modification of commercial Celgard series separator.In this paper,the latest research status of separator modification of lithium-sulfur battery is reviewed from the aspects of types and mechanism of modified membranes coating.
