Them ech anism o f w ood carbonization w as summ arized, and the basic properties of wood charcoal and the influencing factors w ere analyzed. The research progress on functional conductive ch arcoal at hom e and abroad w as rev iew ed, and the research focu s in the future w as put forw ard. The study w as ami ed to provide scient ific b asis for the developm ent and utilization of new types o f functional m aterials. K ey words: w ood pyro lysis, h igh tem perature carbonizat ion, ap
