Battery material diversification for EVs

In early August 2026, major automakers began testing next‑generation battery chemistries. General Motors and Mercedes‑Benz trialed silicon‑anode cells that replace part of the graphite anode with silicon, promising dramatically higher energy density, longer range and rapid charging. At the same time, researchers at Pennsylvania State University demonstrated a process to turn recycled PET plastic into synthetic graphite that outperforms natural graphite, offering a greener, locally sourced feedstock for battery anodes.

A few days later, companies in North America and Europe announced projects to expand the supply of natural and synthetic graphite. In Alaska, Graphite One moved toward a federal decision on its Graphite Creek mine and a planned synthetic‑graphite plant in Ohio. In Canada, Global Battery Materials acquired Lomiko Metals, adding Quebec and Newfoundland‑Labrador graphite projects to its vertically integrated portfolio. Greenland’s Greenroc Strategic Minerals secured a long‑term licence for the Amitsoq deposit, targeting up to 80,000 tonnes of graphite annually by 2030. Parallel to these graphite initiatives, U.S. startups were testing sodium‑ion batteries that replace lithium‑group minerals with common salt, further diversifying the material base for electric‑vehicle batteries.

Together, the snapshots illustrate a rapid shift from laboratory‑scale breakthroughs toward large‑scale resource development and alternative chemistries, all aimed at reducing reliance on Chinese graphite and securing a sustainable supply chain for EV batteries.
