Graphite Anode Battery Technology
Graphite anodes are a crucial component of lithium-ion batteries. The anode is responsible for the storage of energy and the movement of lithium ions from anode to cathode during discharge. They feature high power density, excellent cycling stability, and nontoxic properties.
EVs require a reliable and secure "mine to battery" supply chain to enable the global transition to electric vehicles. This requires an integrated and sustainable mining and processing of graphite. Graphite is a relatively plentiful mineral. However, its availability has been challenged by strict environmental review processes. Currently, about 70-80% of the natural graphite used in EV batteries comes from China.
Graphite prices have increased since January 2021. While the market is expanding, the shortage of natural graphite is not yet solved. A large portion of this global graphite shortage is due to limited capacity.
To address this, major producers are working on expanding integrated graphitization capacity. In addition, new projects are emerging around the world. These include Renascor Resources Limited, a minerals explorer. It has secured approval for PEPR, a second step in a two-stage assessment process.
The Australian company has plans to build a mine and concentrator in the Siviour Graphite Belt in Australia. Eventually, it will be able to produce up to 150,000 tons of graphite concentrate per year.
Unlike natural graphite, synthetic graphite has high purity and is able to sustain long cycle life. This enables faster charging and better battery performance.
Anovion has a proven track record in synthetic graphite manufacturing. With 140 years of combined experience, the company is a leading supplier to several emerging applications.
