An artificial solid electrolyte interphase (SEI) is demonstrated for the efficient and safe operation of a lithium metal anode. Composed of lithium-ion-conducting inorganic nanoparticles within a flexible polymer binder matrix, the rationally designed artificial SEI not only mechanically suppresses lithium dendrite formation but also promotes homogeneous lithium-ion flux, significantly enhancing the efficiency and cycle life of the lithium metal anode.
一种人工固体电解质界面(SEI)被证明可有效且安全地用于锂金属阳极的工作。该人工 SEI 由可传导锂离子的无机纳米粒子与柔性聚合物粘结剂基质组成,其合理设计不仅可机械抑制锂枝晶的形成,还可促进锂离子的均匀通量,从而显著提高锂金属阳极的效率和循环寿命。
