We are grateful for the Minister to take time to visit the science exhibition ship MS Wissenschaft, anchoring in Saarbrücken, Germany. We discussed climate change, scientific discoveries, basic and applied research – specifically as it pertains to our research on lithium-ion battery recycling.

New collaborative paper (Victor H. R. Souza) published in Journal of Power Sources. To support the energy transition, we developed freestanding electrodes combining reduced graphene oxide, polyaniline, and nickel hexacyanoferrate (NiHCF), which is a promising material for aqueous batteries due to its long cycle life and redox-active structure. These rGO/PAni/NiHCF films achieve high specific capacities (up to 83 mAh/g) and integrate both active material and current collector in one, offering a compact and efficient solution for energy storage.

We are grateful for the Minister visiting our group to learn more about the EFRE-funded eLiFlow project to continuously harvest lithium-ions from aqueous solutions.
