In part 1 the course will revise key concepts and models of electrode interfaces before covering in detail examples of electrochemical interfaces for energy conversion including electrocatalysis for hydrogen production, carbon dioxide conversion; and also the principles light driven energy conversion. In part 2 the electrochemical principles of energy storage systems and the principles of design and operation of the current state-of-the-art and the potential future battery technologies. The course revises and builds on the contents of core inorganic and physical chemistry modules from years 1 and 2.
