▎ 摘　　要

The possibility of protecting the current collector of the cathode of a lithium-ion battery from the corrosive agents of electrolyte by creating a protective shell of reduced graphene oxide on the collector surface was studied. The positive effect was found to be a decrease in the degree of Faraday processes. The results of scanning electron microscopy, XRD analysis, Raman spectroscopy, and cyclic voltammetry were presented.
