SUMMARY OF WINNING ENTRY
Investigated electrochemical intercalation of graphite and the thermodynamics of the battery charging/discharging processes
Professor Rachid Yazami pioneered the exploration of reversible electrochemical intercalation of Lithium-ions into graphite, laying the foundation for the development of modern Lithium-ion batteries. His research delved into combining nanomaterials such as nano-silicon, carbon nanotubes, and graphene with other materials such as graphite and carbon black in the anode of batteries. Furthermore, his work also has brought extensive insights into the thermodynamics of battery charging and discharging processes, which was described in the fundamental Yazami’s Battery Theorem. Until today, he remains at the forefront of innovation, continuing his exploration into novel cathode, anode materials, and the fundamental processes of battery operation.
