Abstract

The growth of dendrites greatly hinders the practical applications of lithium metal batteries. In this work, we adopt an automatic spreading method to coat graphene oxide (GO) layers on metallic lithium foil to form a composite electrode. The GO layers are distributed homogeneously and show low roughness on the metallic lithium foil. The electrochemical performance of GO modified Li (GO/Li) electrodes have been thoroughly studied. The GO/Li electrode displays enhanced electrochemical performances in a lithium–sulfur full battery, and better cycling stability in symmetric lithium–metal coin cells than the unmodified pure Li electrode. In addition, the growth of dendritic Li is successfully suppressed in the GO/Li electrode.
