New paper published in Energy & Environmental Materials. A few years ago, then-PhD-student Zhang Yuan explored with us the adoption of a fuel cell for continuous water desalination. Basically, a fuel cell can be “fooled” to desalinate an inflowing water stream by replacing the common proton exchange membrane with a flow channel, contained within a pair of an anion and a cation exchange membrane. Thereby, while consuming fuel (e.g., hydrogen and oxygen), electricity is generated and water desalted all at once. Now, we have moved one step further: making fuel cell desalination lithium-ion selective for direct lithium-ion extraction from seawater or mine water (other water media work too).
A titania-coated electrode in our fuel cell achieves a 95% lithium-ion purity and produces 10.23 Wh of energy per gram of lithium. Thanks to atomic layer deposition, we’ve significantly improved the electrode’s uniformity, stability, and electrocatalytic activity, maintaining stability even after 2000 cycles.

It is a tradition at the Natural Science Faculty of Universität des Saarlandes to have the annual PhD Day in the Aula. This year, 60 PhD student presented their research, ranging from artificial muscles, to much real mucus, from 3D printed nanofluids to very solid metals, from quantum communication to quorum sensing inhibitors. From our team:
Nikolaos Papadopoulos shared his insights into electrochemical modelling. 薛丽颖 introduced us to the concept of high-entropy battery electrodes. Jean Gustavo De Andrade Ruthes demonstrated the exciting field of gel electrolytes. Panyu Ren taught us the value of electrochemical ion separation. And Le Thao presented the latest results from our collaboration with the spherogel team of Michael Elsaesser on hybrid carbon spherogels for battery applications.
