Abdelfattah Mahmoud received his PhD in Materials Science in December 2012, from Cadi Ayyad University in Marrakech (Morocco) in collaboration with Montpellier University (France) and the Institute of Material science of Madrid (Spain). His PhD focused on the development of electrode materials (MnSn2, LiCo2/3Ni1/6Mn1/6O2, Li4Ti5O12) for high energy density lithium-ion batteries. Abdel then moved to the research centre of Juelich (Germany) on 2013, where he was involved in the development of the applications of Mossbauer spectroscopy and synchrotron techniques to investigate energy materials (Li/Na-ion batteries and fuel cells). In December 2015, Abdel joined the University of Liege (Research project RESIBAT) where his work at GREENMAT is the synthesis and characterization of new electrode materials for rechargeable batteries and mainly the valorization of the silicon extracted from solar panels as anode material for Li-ion batteries.


One of the main challenges of energy storage devices is the development of cheap and eco-friendly battery systems with high safety and high energy density. Battery is the best choice to store electricity in the form of chemical energy when considering the flexibility and constitute the limiting components in shift from petrol powered to electric vehicles, while also the use of the more renewable energy on the grid. Since the nineties, lithium-ion batteries (LIBs) have become one of the dominant technologies, however, lithium ion batteries cannot stand alone to fulfill future needs. Due to the high abundance of sodium and potassium, Na-ion batteries and K-ion batteries have recently emerged as highly promising candidates.

Electrode materials present the key component for the development for the new generation of the rechargeable batteries. This seminar will focus on the design, synthesis and characterization of high capacity phosphate electrode materials for Alkali-ion batteries with special attention paid to the control of microstructure as a tool to optimize their electrochemical properties.  The materials have been prepared using facile, inexpensive and suitable synthesis methods (hydrothermal and spray drying) for powders with high homogeneity, leading to excellent electrochemical properties [1-6].
