CTOnews.com, October 22 / PRNewswire-FirstCall-Asianet /-- researchers at Chalms University of Technology in Sweden have proposed a new way to recover metal from waste batteries of electric vehicles, which can recover 100% aluminum and 98% lithium from batteries, while minimizing losses of valuable raw materials such as nickel, cobalt and manganese.

According to reports, the researchers used a new formula containing oxalic acid (CTOnews.com Note: oxalic acid can be extracted from plants such as spinach, is an environmentally friendly ingredient). When the used car battery unit is crushed, the black powder content is dissolved in the liquid containing oxalic acid. After a period of time, the black powder is filtered, and aluminum and lithium will remain in the turquoise liquid. Other metals such as nickel, cobalt and manganese appear in a dark solid state.

The next step in the recycling process at ▲ Chalms University of Technology is to separate aluminum and lithium, and the researchers say it is "not difficult" to separate metals because of their different properties. "our method provides a promising new way for battery recycling and is definitely worthy of further exploration."

Martina Petranikova, an associate professor in the Department of Chemistry and Chemical Engineering at Chalms University of Technology, said this method can be scaled up in the hope that it will be used in industry in the next few years. According to reports, her research team has worked with a number of local companies to develop electric vehicle battery recycling technology, and is also a partner of Volvo.
