Outline of Research at the Start

In this work, 100% isotope-labeled free-standing 13C electrodes with hierarchical porous structure will be synthesized and used as model electrodes for fundamental studies on Li-O2 batteries. By combining 13C electrodes and in situ techniques, the complex corrosion reactions can be decoupled.
