Course description and aims

To acquire the applied and practical skills of electrochemistry is needed to understand the features, functions and issues of electrochemical devices that are widely used in our society, such as batteries and fuel cells. This course gives profound understanding of evaluation and analysis methods based on electrochemical concepts (thermodynamics, kinetics, and so on). The participants study structural characterizations which gives further understanding of electrochemical phenomena to acquire practical senses to the electrochemical devices.

Student learning outcomes

By the end of this course, students will able to:
1) Explain the concepts of electrochemical device applications based on a) the basic concepts of electrochemistry such as electrodes, electrolytes, interface, potential and b) the relationships among potential, current and time governed by equilibrium and kinetics.
2) Explain principles of electrochemical measurements used for analysis of electrochemical devices.
3) Explain the features, usage and issues of rechargeable batteries and fuel cells considering their components and characteristics.
4) Explain the effects of material and device structures on electrochemical phenomena and the characterization methods.

Keywords

electrochemistry, energy conversion, electrochemical interface, electrochemical reactions (equilibrium and kinetics), electrochemical measurements, rechargeable batteries, fuel cells

Competencies that will be developed

✔ Specialist skills Intercultural skills Communication skills Critical thinking skills ✔ Practical and/or problem-solving skills

Class flow

Individual topics will be lectured. Towards the end of class, if needed, students are given exercise problems related to the lecture given that day to solve. To prepare for class, students should read the course schedule section and check what topics will be covered. Required learning should be completed outside of the classroom for preparation and review purposes.

Course schedule/Required learning

  Course schedule Required learning
Class 1 Introduction Review of basic electrochemical concepts learned in Advanced Electrochemistry I. Explain the importance of analytical techniques (including operand measurements) utilized in the actual device development research.
Class 2 Interfacial reactions of lithium batteries Explain the importance of observing interfacial structures to elucidate electrochemical reactions in lithium-ion batteries and the methods.
Class 3 Electrochemical reactions in all solid-state batteries Explain the principles, materials, applications, and challenges of all-solid-state batteries.
Class 4 Metal–air batteries and their reaction kinetics Metal–air batteries with high theoretical energy density suffered from reaction kinetics of both dissolution/deposition reactions of metal and reduction/evolution of oxygen. The goal of this lecture is to explain how the reaction mechanism can be clarified by operando analysis of metal electrodes and by rotating electrode techniques to capture the intermediate species.
Class 5 Electrode reaction kinetics of biphasic reactions Biphasic reactions are one of important electrode reactions and their phase transitions can often be expressed using the first-order reaction kinetics. The goal of this lecture is to explain the reaction kinetics of lithium iron phosphate and lithium manganese spinel electrodes analyzed by potential-step methods.
Class 6 Electrode materials and their reactions for sulfide-type all-solid-state batteries All-solid-state lithium batteries are expected as the next generation energy storage. The goal of this lecture is to understand the categorizes such as oxide-based and sulfide-based battery systems, and explain the characteristics of the high-capacity cathodes used in the sulfide-based battery system.
Class 7 Experiments, theory and informatics on exploration and evaluation of solid materials Solid-state material exploration is important for the development of all-solid-state batteries. The goal of this lecture is to understand and explain the various methods used in the search for new materials.

Out-of-Class Study Time (Preparation and Review)

To enhance effective learning, students are encouraged to spend approximately 100 minutes preparing for class and another 100 minutes reviewing class content afterwards (including assignments) for each class.
They should do so by referring to textbooks and other course material.
