Recycling of electric car batteries is explored in new research project

Chalmers University of Technology

​The performance and quality of battery cells made from materials from used electric car batteries will now be tested, in a collaboration between Volvo Cars, Northvolt, researchers from Chalmers Chemistry department and Uppsala University. A hydrometallurgical method that the Chalmers researchers has been part of developing, will be used in the project. ​How the performance of the battery cell is affected when it is made from recycled materials is an important issue to investigate, if we shall be able to reduce the use of critical metals and develop a sustainable production of electric cars. In this project the impact of non-metallic contaminants on battery performance, will be studied, which has not been published ant research on jet. Battery aging is already an important property for the lifetime of a car’s battery. The project aims to investigate whether there are any new aging phenomena that occur in cells made from recycled material, compared with when new material has been used.

Martina Petranikova, Associate Professor, at the Department of Chemistry and Chemical Engineering, is leading the project from Chalmers part. She commented on it in an interview in the magazine Ny Teknik recently.
“Before we start using recycled metals, we therefor need to define the effects through research to be sure that battery performance and safety are not negatively affected,” says Martina Petranikova.
