New paper published in ChemSusChem. Our joint work with the Leibniz Institute for Plasma Science and Technology (INP Greifswald) demonstrates mixed Ti-Nb metal oxide electrodes for lithium ion application. Using electrospinning, the fiber mats are free of binder, free-standing, and can be directly used as electrodes. Per nanoscale engineering, the fibers also already contained sufficient amounts of conductive carbon within each fiber, so that no additional conductive phase needed to be added.
