Modification of lithium/electrolyte interface by plasma polymerization of 1,1-difluoroethene

Surface of lithium electrodes was covered by an ultra-thin and uniform solid polymer electrolyte layer conductive for lithium ion which was prepared from 1,1-difluoroethene by plasma polymerization. The solid polymer electrolyte showed room temperature conductivity of 3 × 10 −8 S cm −1. Lithium was...

Description
Summary:Surface of lithium electrodes was covered by an ultra-thin and uniform solid polymer electrolyte layer conductive for lithium ion which was prepared from 1,1-difluoroethene by plasma polymerization. The solid polymer electrolyte showed room temperature conductivity of 3 × 10 −8 S cm −1. Lithium was deposited (1 C cm −2) on the surface modified lithium electrode in 1 M LiClO 4/proplylene carbonate. Scanning electron microscopy observation suggests that dendritic growth of lithum was suppressed on the lithium electrodes surface modified by the ultra-thin solid polymer electrolyte.
