Quality control: Graphitization degree and orientation index in graphite anode materials
Modern batteries, like Li-ion, have revolutionized our day-to-day life – from enabling smart mobile devices to pollution-free electric cars and intelligent power-management solutions. Batteries also hold the potential to be economical solutions for mass energy storage, complementing renewable energy resources for power grid applications. Irrespective of the cathode chemistry, which can be either LFP or NCM-based, most commercial batteries use graphite as an anode material. Battery-grade graphite is sourced from one of two sources: natural or synthetic. Natural graphite is mined, whereas synthetic graphite is produced from petroleum coke (leftover carbon from petroleum refining) by heating it to temperatures above 2500°C. Favored by EV battery manufacturers for its consistency and performance, synthetic graphite dominates the anode supply chain.
