Abstract:
In an example of a method for making a hollow carbon material, a carbon black particle is obtained. The carbon black particle has a concentric crystallite structure with an at least partially amorphous carbon core and a graphitic carbon shell surrounding the at least partially amorphous carbon core. The carbon black particle is exposed to any of a heat treatment, a chemical treatment, or an electrochemical treatment which removes the at least partially amorphous carbon core to form the hollow carbon material.
