Conférence du Dr. Oleksandr Magazynskyy de la "School of Materials Science and Engineering" d'Atlanta (États-Unis)

Gleb Yushin is a Professor at the School of Materials and Engineering at Georgia Institute of Technology. His research group has developing nano-scale synthesis strategies to bypass macro-scale limitations of energy and structural materials with applications in clean tech, electric vehicles, wearable electronics, and more. It develops of novel processing techniques to substantially improve in the conductivity of solid electrolytes to enable and improve high energy density battery technologies. Its research projects are focused on gaining fundamental understanding of the impacts of chemistry, microstructure and composition on physical properties, electrochemical stability, metal ion diffusion and sensitivity to environment in several classes of solid state electrolytes. In the laboratory of Prof. Yushin, a highly innovative approach of nanomaterial synthesis based on the strain energy minimization at the boundary of the phase transformation front was discovered. Such an approach allowed developing cheap and environmentally friendly synthesis of flexible alumina nanowires and nanowire-based separator membranes for safer Li-ion batteries. Laboratory of Prof. Yushin is conducting fundamental studies of the interactions of conversion-type active materials with electrolyte components and additionally exploring approaches to overcome the known shortcomings observed in conversion-type electrodes.
