While lithium-ion batteries dominate the market, researchers have developed a more energy-efficient way to extract lithium from rocks. This process uses less energy than current methods and recycles its starting chemicals, producing byproducts that can be sold.

The new method targets spodumene, which is globally abundant but currently hard to process due to high energy costs. By heating the mineral to around 1,000°C and using sulfuric acid, lithium can be extracted more efficiently. What sets this process apart is its ability to regenerate key chemicals used at the start of production, making it both sustainable and cost-effective.

Currently, lithium-rich brines are primarily found in South America, limiting supply diversity. This new technique could unlock global reserves, potentially reducing reliance on current sources and providing a more stable supply chain for battery manufacturers.

The collaboration between MIT researchers and local companies ensures that the process is not only effective but also practical for commercial use. By repurposing silicon and aluminum waste into commercially valuable products, this innovation promises to have a significant impact on the future of lithium extraction and battery technology.
