Fall 2022 Solid State Ionics (MSE 5007, Westlake University)

Course description: This course serves as a comprehensive introduction to the fundamental knowledge and methodology in the field of solid state ionics. Solid state ionic materials have wide applications in energy conversion and storage, catalysis, sensing, as well as neuromorphic computing and memory. This course will introduce the underlying principles of ionic point defect behavior that governs the performance of solid ionic materials in these applications. These principles include point defect formation and defect chemical reactions, ion transport, migration and chemical (ambipolar) diffusion, solid-state electrochemistry, electrocatalysis and irreversible thermodynamics. Solid-state electrochemical techniques, frontiers in solid state ionics and case studies will also be discussed in this course.
