Graphite specific capacity

WebSynthetic graphite is made from fossil fuels (petroleum coke). Typically coal-based needle coke, is crushed, graphitized, and demagnetized to produce synthetic graphite. Battery makers use a blend of CSG and synthetic graphite to form the Li-Ion battery anode. WebNov 14, 2024 · In 1991, using graphite anodes with a flat potential profile below 0.5 V vs. Li/Li + and a considerable specific capacity of 372 mAh g −1 (corresponding to one lithium per hexagonal carbon ring, i.e., LiC 6) led to increasing the volumetric and gravimetric energy density of LIBs up to 400 Wh L −1 and 165 Wh kg −1, respectively [ 5 ].
