[Summary of the course] In this course, the redox reactions and the electrochemical cells, both basic principles of the battery, are first described. Next, phase diagram is described in order to understand the complex phase transformation of inorganic compounds. In addition, basic principles of magnetism and roles of the localized spins are explained.
[Aim of the course] The battery and the magnet are key elements that are indispensable to the power storage and electric motors, respectively, and learning materials chemistry provides effective means to solve environmental and energy issues. Although they are familiar, the principle is not as simple as apparent functionality. Elements used in these applications include rare earths and noble metals, which are desired to be replaced by abundant elements. Given such social backgrounds, batteries and the magnets can be regarded as subjects for improving students’ critical thinking along specialists’ knowledge on the reactivity and physical properties of the solids. From this point of view, this course encourages students to discuss and do exercises about problems.
At the end of this course, students will be able to:
1) explain the principles of battery and magnets, synthesis methods and reactivity of materials used for them.
2) improve their ability to explore new compounds and new synthesis methods for battery and magnets using periodic table and phase diagram.

This course will proceed in the following order: (1) electrochemistry, (2) phase diagram, and (3) magnetism. In the last class, exercise problems and explanation of the answers will be given to assess the students’ level of understanding.
|Course schedule||Required learning|
|Class 1||Introduction to redox reactions||Explain the course objectives.|
|Class 2||Electrochemical reactions||Derive redox pair of specific reaction based on the electrochemical series.|
|Class 3||Phase diagrams of inorganic compounds||Read fraction and composition of a phase described in a phase diagram.|
|Class 4||Phase transformations and solid-state reactions||Read feature of specific phase transformations from a phase diagram.|
|Class 5||Magnetism and spin-spin interactions||Explain types of magnetism and spin-spin interactions.|
|Class 6||Magnetic compounds||Derive types of exchange interaction from chemical formula of transition-metal oxides.|
|Class 7||Exercise problems to assess the students’ level of understanding and interpretation of the answers||Use the exercise problems to better understand the topics covered, and evaluate one’s own progress.|
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.
