Li-Anode Protective Layers for Li Rechargeable Batteries via Layer-by-Layer Approaches

Li–anode protective layers were fabricated using layer-by-layer (LBL) assembly. The simple deposition on a polymer support membrane of an ionic conductive polymer and graphene oxide (GO) resulted in high ionic conductivity, controlled electrolyte permeability, and high-Li-transfer number. The uniformly coated LbL protective layer suppressed Li dendritic growth on the Li surface and improved Li electrode cyclability. This makes it possible to use Li metal for rechargeable Li batteries.
