Abstract

A method for manufacturing a supercapacitor carbon material includes: (A), allowing heavy oil to be subjected to a first heat treatment to form a soft carbon precursor, a mesophase structure ratio of the soft carbon precursor is greater than 50%, a QI value is 95~98%, and a TI value is 89~91%; (B), grinding and grading the soft carbon precursor, then mixing it with an activator and a passivator to form a mixture; (C), activating and carbonizing the mixture to form a carbonized component, the carbonized component comprising the residual activator and passivator; (D), washing the carbonized component with water to remove the residual activator, removing the residual passivator with ethanol, then pickling and washing with water to neutral, then drying to obtain an activated carbon material; (E), allowing the activated carbon material to be subjected to a second heat treatment to form a supercapacitor carbon material.
