These have laid a good foundation for its application in the lithium ion battery industry. Natural graphite is divided into amorphous graphite (earth graphite or microcrystalline graphite) and flake graphite. The theoretical capacity is 372 mAh/g. Amorphous graphite has a low purity and a graphite interplanar spacing (d002) of 0.336 nm.
