Spherical graphite is a crucial ingredient to the efficient operation of lithium ion batteries (LiB). Spherical graphite is the key component of the anode of a LiB which without, the LiB would not function. Historically SPG has been derived from synthetic graphite, a significantly more costly option when compared against natural flake graphite ...

Graphite From Coal Seam Metamorphism ("Amorphous" Graphite) Some graphite forms from the metamorphism of coal seams. The organic material in coal is composed mainly of carbon, oxygen, hydrogen, nitrogen, and sulfur. The heat of metamorphism destroys the organic molecules of coal, volatilizing the oxygen, hydrogen, nitrogen, and sulfur.

Graphitization is the formation of graphite (free carbon) in iron or low-alloy steel, which occurs when their components are exposed to elevated temperatures over a long period. The formation of graphite is due to the nucleation and growth process that occurs when the steel is exposed to temperatures above 800°F (426°C).

In this process, agglomerated graphite grains are produced for use as carburizer and carbon additives. Intercalation. Due to its extreme anisotropy, the graphite crystal enables salts to be intercalation in its structure. When heated, these salts evaporate, causing the disruption of inter-planar connections, "expanding" the graphite.
