According to Nikkei Asia, researchers in Australia have developed a method to "fingerprint" lithium. This technique, developed by the John de Laeter Centre at Curtin University, uses unique chemical properties to identify the origin of lithium, potentially down to the specific mine.
This method can also be adapted for other critical minerals and metals, providing insights into their downstream processing and refining. Researchers claim this method is crucial for green energy technologies and mineral trade, enhancing transparency in the critical minerals supply chain.
Australia has been heavily investing in the critical minerals sector, recently allocating approximately US$385 million to support sustainably produced minerals. Australia had also signed a new agreement with the European Union to emphasize creating resilient supply chains and aligning mineral pricing with high environmental, social, and governance (ESG) standards.
As a key source of battery metals like lithium and nickel, Australia faces high production costs and competition from developing countries. Therefore, certifications like this fingerprinting method may bolster its position in the supply chain and achieve premium pricing, aligning with the risk mitigation strategies of Western countries.
