Researchers have created a method of recycling nearly 50% of the lithium in the millions of batteries that are discarded February 7 . Rafia Afroz , from the International Islamic University Malaysia at the Department of Mechanical Engineering , and Ataur Rahman , of the Department of Economics , created a hydrometallurgical method to extract nearly 50% of lithium and nearly 25% of cobalt from scrap batteries. Citation: The pair baked the batteries at a high temperature before treating them with strong acids such as hydrogen peroxide. The extracted materials can be reused in new batteries, with the remaining liquid waste being treated for safe disposal.
