Dimitrios Chatzogiannakis is a predoctoral researcher, member of the Advanced Electrode Materials group at CIC EnergiGUNE and Solid State Chemistry group at ICMAB-CSIC. He is part of DESTINY MSCA COFUND PhD programme where he is co-supervised by Prof. Rosa Palacin (ICMAB-CSIC) and Dr. Montserrat Casas Cabanas (CIC EnergiGUNE). His work focuses on cathodes that utilize blends of active materials with the goal to improve their performance but also understand the synergetic effects present in such complex systems. This is achieved mainly, but not exclusively, through electrochemical and X-ray diffraction experiments. He has worked with energy storage-related subjects since he obtained his Bachelor´s degree, first as a Master´s student (University of Crete, IESL-FORTH), then as a research assistant (IESL-FORTH) and finally as an Erasmus+ exchange student (CIC EnergiGUNE). His master thesis, on PEO-based polymer electrolytes for Lithium solid-state batteries, supervised by Prof. Emmanouil Glynos and Prof. Spiros Anastasiadis was awarded Cum Laude. This gave him both the motive and the opportunity to pursue a battery-related PhD, through the very different but exciting perspective of the electrodes.
