About Flake Graphite
Graphite is an essential material in the lithium-ion batteries that power electric vehicles. It is the single largest component by weight in every EV battery, with each vehicle requiring 50 to 100 kilograms of graphite. There are no known substitutes.
Currently, China produces approximately 82% of the world's natural graphite supply. Canada produces less than 1%, and the United States produces none.
Types of Graphite
Flake Graphite
Flake graphite is the most important type for battery applications. It occurs naturally as discrete flakes in metamorphic rocks and is classified by size: jumbo (+50 mesh), large (-50 to +80 mesh), medium (-80 to +100 mesh), and fine (-100 mesh). Large and jumbo flake graphite commands premium pricing.
Amorphous Graphite
Amorphous graphite is the most abundant and least valuable form. It is used primarily in steel manufacturing, brake linings, foundry applications, and lubricants.
Vein Graphite
Vein graphite is the rarest and highest purity form, occurring naturally at 90-99% carbon content. Found primarily in Sri Lanka, it commands the highest prices.
