Although we call them lithium-ion batteries, lithium makes up only about 2% of the total volume of the battery cell. There is as much as 10-20 times as much graphite in a lithium-ion battery. The anode is made up of powdered graphite that is spread, along with a binder, on a thin aluminum charge collector.
And as the capacity of graphite electrode will approach its theoretical upper limit, the research scope of developing suitable negative electrode materials for next-generation of low-cost, fast-charging, high energy density lithium-ion batteries is expected to continue to expand in the coming years.
The increasing demand for lithium-ion batteries, driven by the growing EV market and renewable energy storage applications, is a significant driver for graphite consumption. As the world races towards a more sustainable future, the demand for graphite in lithium-ion batteries is poised to skyrocket.
Graphite for batteries currently accounts to only 5 percent of the global demand. Graphite comes in two forms: natural graphite from mines and synthetic graphite from petroleum coke. Both types are used for Li-ion anode material with 55 percent gravitating towards synthetic and the balance to natural graphite.
