Title: Electrochemistry in the molten state: from sustainable metal extraction to materials fundamentals

In the context of 9 billion people by 2050 and issues such as greenhouse gas emissions, my research group aims at developing alternative approaches for metals extraction and processing. The electrochemistry of the molten state is an integral part of our endeavor, compatible with the deployment of sustainable electric power generation. This seminar offers to report electrochemical studies of a subset of molten oxide and sulfide systems. Our results show that the molten state offers unique functionalities (enhanced mass transport, high conductivity, electronic conductivity, thermoelectric power) and that electrochemistry is uniquely positioned to probe the structure and physical chemistry of those systems. In addition, our results provide valuable thermodynamic information, and our experimental developments suggest a faster path to experimental data, along with an improvement in the prediction and modeling capacity of the molten state.
