Audi and Umicore develop closed loop battery recycling
Audi and Umicore say that the company have successfully completed phase one of their strategic research cooperation for battery recycling.
The two partners are developing a closed loop for components of high-voltage batteries that can be used again and again. Particularly valuable materials are set to become available in a raw materials bank. Already before the start of the cooperation with Umicore in June 2018, Audi had analysed the batteries in the A3 e-tron plug-in hybrid car and defined ways of recycling. Together with the material technology experts, the car manufacturer then determined the possible recycling rates for battery components such as cobalt, nickel and copper. The result: In laboratory tests, more than 95 percent of these elements can be recovered and reused, a press release reads. The move now for the partners is to begin developing specific recycling concepts. The focus is on the so-called closedloop approach. In such a closed cycle, valuable elements from batteries flow into new products at the end of their lifecycle and are thus reused. The Ingolstadt-based company is now applying this approach to the high-voltage batteries in the new Audi e-tron electric car. The aim is to gain insights into the purity of the recovered materials, recycling rates and the economic feasibility of concepts such as a raw materials bank. Security of supply and shorter delivery cycles are the goals. "We want to be a pioneer and to promote recycling processes. This is also an element of our program to reduce CO2 emissions in procurement", says Bernd Martens, Member of the Board of Management for Procurement and IT at AUDI AG, in the release.
