WP2. Materials and technologies for sustainable EV batteries in a circular economy. Lead: Matylda N. Guzik

Li-ion battery packs recovered from end-of-life EVs present potential technological opportunities for improving both material efficiency and energy systems. Closed-loop recycling processes, where whole EV batteries and/or their constituent minerals and compounds are kept in a perpetual cycle of use and reuse, are getting increasingly important for reducing primary material demand. At the same time, waste EV battery packs can be reutilized as a stationary energy storage solution, facilitating the integration of wind and/or solar energy. This approach is promising but still requires modeling & pilot tests to be broadly implemented.

The RQs to be answered in WP2 are: 1) What is the feasibility of the 7R’s circular economy approach in the sustainable EV battery production & utilization?; 2) New vs. used/waste EV batteries in RES: what are the technical performance differences?; 3) How to improve grid stability & resilience with integrated new vs. used/waste EV batteries during load changes, failures & disruptive conditions?; and 4) How to implement an energy management system for zero-energy buildings by integration of used/waste EV batteries with RES?
