Abstract A highly crystalline graphite powder was prepared from the low temperature (800–1000 °C) graphitization of renewable hard carbon precursors using a magnesium catalyst. The resulting particles are composed Voronoi‐tessellated regions comprising irregular sheets; each region having small “seed” particle located near their centroid on surface. This suggests nucleated outward growth graphitic carbon, which has not been previously observed. Each seed consists spheroidal shell inside hexagonal platelets perpendicularly affixed. results in unique high surface area with degree that is made feedstocks at temperatures far below conventionally used for artificial graphites.
