P - PHOSPHORUS DOPED and phosphate functionalized REDUCED GRAPHENE OXIDE ARTIFICIAL SOLID ELECTROLYTE INTERPHASE AND ANODE FOR LITHIUM METAL BATTERY COMPRISING THE SAME

摘要

The present invention relates to a solid electrolyte interphase (SEI) for secondary battery negative electrode protection comprising reduced graphene oxide nanoparticles doped with phosphorus (P). Accordingly, an artificial SEI layer can be formed as a protective layer on a lithium negative electrode to stabilize the electrochemical performance of a lithium metal battery.
