Recycling of spent batteries is one of the most important activities to support and to secure the raw materials supply for battery productions. There has been a significant development in the recycling technologies in recent years and more will come. The change is affected by the need for raw materials and will be heavily influenced by new battery directives in EU. We are happy to welcome Martina Petranikova, Associate Professor at Chalmers University of Technology, as speaker at Battery Tech for EV 2022. Martina has more than 14 years of experience in waste management of spent batteries of all chemistries with focus on the material recycling. We asked Martina a few questions before the event.
