MULTI-LAYER STRUCTURES PREPARED BY LAYER-BY-LAYER ASSEMBLY

摘要

A protective layer can be deposited on a surface of an porous polymer separator placing on a Li-metal electrode to protect against adverse electrochemical activity in a battery. The protective layer can be a multilayered structure including graphene oxide.

1. A method of preparing a multi-layer structure on a substrate comprising:
forming a pair of bilayers on a surface of the substrate,
the first bilayer including a first material and a second material wherein the first material and the second material are oppositely charged materials or materials otherwise having affinity for each other;the second bilayer including a third material and a fourth material wherein the third material and the fourth material are oppositely charged materials or materials otherwise having affinity for each other; andthe pair of bilayers including ion-conductive polymer and a barrier layer.
