By in situ nitrogen doping and structural hybridization of carbon nanotubes (CNTs) and graphene via a two-step chemical vapor deposition (CVD), scientists have fabricated nitrogen-doped aligned carbon nanotube/graphene (N-ACNT/G) sandwiches with three-dimensional (3D) electron transfer pathways, interconnected ion diffusion channels, and enhanced interfacial affinity and activity. The as-fabricated N-ACNT/G sandwiches, described in the journal Advanced Materials on Sep 17 2014, demonstrated high-rate performances in lithium-sulfur (Li-S) batteries.
