95% of worthwhile battery supplies may be recycled
Audi, in partnership with Umicore, develops closed-loop battery recycling, which signifies that worthwhile battery supplies shall be recycled to be used in the identical utility in a brand new battery pack.
The analysis in small-scale was finished utilizing batteries from the A3 e-tron plug-in hybrids and on the lab stage as much as 95% of worthwhile battery supplies (resembling cobalt, nickel and copper) was capable of be recycled.
As a result of batteries include lots of not so worthwhile supplies, we don’t know what quantity shall be recycled and what utilized, nevertheless it appears lower than 95%.
The recycled supplies will go to a uncooked supplies financial institution and when their purity is adequate, new batteries may be made.
“Milestone reached: Audi and Umicore have efficiently accomplished part certainly one of their strategic analysis cooperation for battery recycling. The 2 companions are creating a closed loop for parts of high-voltage batteries that can be utilized time and again. Notably worthwhile supplies are set to turn out to be out there in a uncooked supplies financial institution.
Already earlier than the beginning of the cooperation with Umicore in June 2018, Audi had analyzed the batteries within the A3 e-tron plug-in hybrid automotive and outlined methods of recycling. Along with the fabric know-how specialists, the automotive producer then decided the potential recycling charges for battery parts resembling cobalt, nickel and copper. The end result: In laboratory exams, greater than 95 p.c of those components may be recovered and reused.
The companions at the moment are creating particular recycling ideas. The main target is on the so-called closed-loop method. In such a closed cycle, worthwhile components from batteries stream into new merchandise on the finish of their lifecycle and are thus reused. The Ingolstadt-based firm is now making use of this method to the high-voltage batteries within the new Audi e-tron electrical automotive. The goal is to achieve insights into the purity of the recovered supplies, recycling charges and the financial feasibility of ideas resembling a uncooked supplies financial institution. Safety of provide and shorter supply cycles are the targets. “We need to be a pioneer and to advertise recycling processes. That is additionally a component of our program to cut back CO2 emissions in procurement,” says Bernd Martens, Member of the Board of Administration for Procurement and IT at AUDI AG.
For Audi, battery recycling is a key aspect of sustainable electrical mobility. From the extraction of uncooked supplies to the CO2-neutral e-tron plant in Brussels to the recycling of parts, the premium model is dedicated to environmentally suitable ideas alongside its whole worth chain”
