Magnified image with the scanning electron microscope of the structured 3D anode used in the project. The core of the electrode is made of carbon bundles (black; approx. 10 µm in diameter), each of which is coated with zinc oxide (white; approx. 1 µm thick). This is where the lithium ions from the electrolyte are stored. Picture credits: Julian J. A. Kreißl , B.Mogwitz. Reprinted with permission from ACS Appl. Mater. Interfaces 2021, 13, 30, 35625-35638.
