In this latest publication from the Chair of Technical Electrochemistry, researchers developed five analytical techniques to study lithium/proton (Li+/H+) exchange in nickel-rich cathode active materials (CAMs) for lithium-ion batteries, revealing the effects of washing parameters on proton content and providing insights essential for improving sustainable CAM processing.
