A 3D conductive scaffold with lithiophilic modification for stable lithium metal batteries

Abstract

A 3D lithiophilic N-doped graphene/nickel foam (NGNF) scaffold to host Li has been successfully prepared by a simple hydrothermal method. This scaffold can improve the poor lithiophilicity of nickel foam (NF) due to the presence of N-doped graphene (NG) with lithiophilic functional groups while maintaining its 3D porous electrode structure, leading to uniform Li plating/stripping.
