| Abstract Scope |
Research findings indicate that under the same conditions:
higher calcination temperatures and finer powders lead to a higher coke yield from the modified coal tar pitch after baking process.
The mixing of calcined coke powder and coal tar pitch forms a new phase—a binder matrix—where the pitch chemically bonds with the surface of the fine coke particles. Higher calcination temperatures and finer powders result in more binder matrix formation and better quality of the baked anode.
The physicochemical properties of green and baked anodes are primarily determined by the characteristics of this binder matrix.
Higher calcination temperatures lead to larger Lc values. When the Lc of calcined coke calcined at 1200–1300°C is controlled within 3.3–3.6 nm, we can produce high-quality carbon anodes with a crystal size of 3.4 ± 0.1 nm and excellent homogeneity. |
