Title: Pyrolytic carbon black composite and method of making the same

Abstract

A method of recovering carbon black includes the step of providing a carbonaceous source material containing carbon black. The carbonaceous source material is contacted with a sulfonation bath to produce a sulfonated material. The sulfonated material is pyrolyzed to produce a carbon black containing product comprising a glassy carbon matrix phase having carbon black dispersed therein. The pyrolysis can be conducted at a temperature from 1100° C. to 1490° C. A method of making a battery electrode and a lithium ion or sodium ion battery is also disclosed.
