In context
Where it fits
Listed in Anode Active Materials. Anode plants are compared on route (natural or synthetic graphite, silicon, hard carbon), the step they own (mining, graphitization, spheroidizing, coating), capacity and cell qualification; purification, graphitization and coating are the bottlenecks, not graphite itself.
