Graphite stocks guide: Here's everything you need to know
An EV lithium-ion battery requires around 60kg of graphite – more than twice the amount of lithium needed. However, Benchmark says natural flake and smaller flake sizes will move into a structural deficit by 2023 as global demand growth for spherical graphite begins to outstrip supply. Over the next decade, anode demand is expected to …

The formation of graphite-rich eclogite vein in S.W.
The graphite-rich eclogite vein (VE) is noticeably darker than the host carbonated eclogites (HE) due to the graphite disseminated in the VE that makes it visually black (Fig. 2). We divided the VE into VE 1 (small veins with width 1–5 cm) and VE 2 (large veins with width > 20cm) according to their width.
