Graphitizable carbon precursor

Needle coke, calcined petroleum coke, and pitch coke — the graphitizable carbon feedstock class that the synthetic route converts into battery-grade graphite. DOE's battery supply-chain map traces the branch from petroleum coke and alternative feedstocks through needle coke into synthetic graphite. A precursor producer enters this corpus only when evidence ties its specific output to battery-anode production.
