According to media reports, researchers at Chalmers University of Technology in Sweden have proposed a new method to efficiently recover metals from used electric vehicle batteries. The method can recover 100% of the aluminum and 98% of the lithium in electric vehicle batteries while minimizing the loss of valuable raw materials such as nickel, cobalt and manganese. The process does not require the use of expensive or harmful chemicals, and the researchers instead used oxalic acid – an organic acid found in plants.

“So far, no one has been able to find the right conditions to use oxalic acid to separate so much lithium while removing all the aluminum. Since all batteries contain aluminum, we need to be able to remove it without losing other metals.” Cha said Léa Rouquette, a doctoral student at the Department of Chemistry and Chemical Engineering at TU Helms.
