Abstract

Increasing the energy density of batteries can accelerate the deployment of electric vehicles, expand the utilization of renewable energy and, in turn, reduce greenhouse gas emissions. Different from commercially available lithium-ion batteries, high-energy-density lithium-metal batteries use metallic lithium instead of graphite as the negative electrode. The commercialization of lithium-metal batteries is hindered by the electrochemical instability of lithium metal. Polymer coatings have shown promise in addressing issues related to each step of heterogeneous lithium deposition. Here we summarize the current understanding of key design principles and highlight relevant coating compositions. Moreover, we discuss high-performing coating–electrolyte pairs and provide an outlook on interface design for novel electrolytes.

聚合物涂层稳定锂金属电极
提高电池的能量密度可以加速电动汽车的部署,扩大可再生能源的利用,从而减少温室气体排放。与市售的锂离子电池不同,高能量密度锂金属电池使用金属锂而不是石墨作为负极。锂金属的电化学不稳定性阻碍了锂金属电池的商业化。聚合物涂层在解决非均相锂沉积的每一步相关问题方面显示出了希望。在这里,我们总结了目前对关键设计原则的理解,并重点介绍了相关的涂层成分。此外,我们还讨论了高性能涂层-电解质对,并对新型电解质的界面设计进行了展望。
