Experts outline cleaner, more resilient supply options for critical graphite mineral

Graphite, the primary anode material in lithium-ion batteries, has become central to energy storage technologies and a growing focus of supply chain concerns. Even as graphite demand is rising faster than lithium demand, global production remains highly concentrated and carbon-intensive.

A perspective article published in Nature Reviews Materials by Rice University researchers traces graphite’s transformation from an industrial commodity to a critical mineral, outlining emerging solutions that could make graphite production cleaner and more resilient, including manufacturing synthetic graphite from renewable sources such as biomass and captured carbon dioxide.

Pulickel Ajayan, Rice’s Benjamin M. and Mary Greenwood Anderson Professor of Engineering and professor of materials science and nanoengineering, and Sohini Bhattacharyya, research scientist in the Ajayan research group, can address follow-up questions on graphite’s role in the energy economy, including:

• How lower-carbon graphite production can strengthen supply security.
• Environmental and supply chain challenges in graphite production.
• Advances in “green” synthetic graphite and recycling of spent battery anodes.
• How industry and policy can help secure sustainable U.S. supply.
