Abstract

Carbon-based materials have been proposed as current collectors for lithium ion batteries (LIBs), however few of them have successfully integrated sp2 carbon and reach in sp3 carbon into one monolithic structure: in a way that sp2 carbon is responsible for electron transfer and sp3 carbon is capable for a high loading of active materials. Here we report an in-situ growth of a nitrogen-doped carbon nanotube (NCNT) on a three-dimensional (3D) graphene network. The proposed structure (NCNT-3DG) is a bio-inspired nanomaterial with a design of a
