Iron, the most common element on Earth, may soon revolutionize the electric car industry. Researchers have discovered a way to use iron as a cathode in lithium-ion batteries, replacing the expensive and scarce metals currently used. This breakthrough could make electric cars cheaper, safer, and more sustainable.
Professor Xiulei “David” Ji and his team at Oregon State University have found a way to make iron react in a manner that increases energy density, making it a viable option for electric car batteries. The cost of iron is significantly lower than nickel and cobalt, which are essential in current battery production. This could potentially cut the cost of batteries in half.
Ji explained that the switch to iron-based cathodes would not require any other changes in battery production, making it a simple and cost-effective transition. The abundance of iron also ensures a steady supply, unlike nickel and cobalt, which are facing shortages due to the high demand for electric vehicles.
While some improvements are still needed for the iron-based cathodes, Ji believes that with investment, this technology could be commercially available in the near future. He emphasized the importance of industry leaders supporting this emerging field to bring about a new era of affordable and sustainable electric cars.
The world may soon see a shift towards iron-based cathodes in lithium-ion batteries, paving the way for a greener and more cost-effective future in the electric vehicle industry.
