Graphite staging

WebGraphite is the crystalline allotropic form of carbon occurs in free state in nature. It can be prepared artificially by heating a mixture of sand and coke in electrical furnace at about 3300 K. In graphite, the carbon atoms are … WebThe presence of lithium plating changed the behavior of the underlying graphite, such as causing co-existence of LiC 6 and graphite in the fully discharged state. Finally, the staging behavior of graphite at different rates was quantified, revealing a high dependency on rate and drastic hysteresis between lithiation and delithiation.
