Electrode design

Posted on

Electrodes are key components for electrochemical devices. Conventional electrodes are films composed of active material in powder form glued together by a polymer binder and electrically often enhanced by a conductive additive. In our team, we explore (1) environmentally friendly polymer binders, (3) binder-free electrodes, (3) flow electrodes as an enabling technology for continuous electrochemical applications, and (4) upscaling perspectives for electrode manufacturing. Our systems range from small coin cells and laboratory cells (2- and 3-electrode configuration) to pouch cells, flow cells, CDI cells, and costum-design electrochemical devices.
