Three Strongly Coupled Allotropes in a Functionalized Porous All-Carbon Nanocomposite as a Superior Anode for Lithium-Ion Batteries

A 3D hierarchically porous architecture built from three different carbon allotropes (graphene, carbon nanotubes, and chitosan-derived porous carbon) has been prepared by using a simple molten-salt synthesis method. The resulting all-carbon nanocomposite is strongly coupled and functionalized with h...

An outstanding reversible specific capacity of 1448mAhg-1 is achieved at 100mAg-1. Even after 200 cycles at 1000mAg-1, a high capacity of 749mAhg-1 is still retained.
