Based on material kinetics, electrochemistry, solid-state physics, and electromagnetism, this course explains important and fundamental concepts to understand and use energy conversion, such as electrochemical reactions with mass transfer, thermal and electric conduction in solid materials, lattice vibration (phonon) that affect light absorption/emission, and the collective motion of electrons in solids.
This course, a fundamental subject for all students of the energy course to study, covers basic knowledge to understand Interdisciplinary Principles of Energy Devices I, II, and Interdisciplinary Energy Materials Science I, II. This course enables students to understand how to effectively use "energy" and what kinds of principles are needed to develop existing devices.
By the end of this course, students will be able to:
1. learn the fundamental knowledge concerning transfers of electrons and ions and electrochemical reactions in various energy devices based on thermodynamics and kinetics.
2. understand the outline of the method of electrochemical measurements that is basic knowledge to characterize the performance of energy devices.
3. learn thermal and electrical conductivity in solid crystals based on the idea of lattice vibration and gain an understanding of the microscopic mechanisms of energy transfer.
4. understand the microscopic mechanisms of the interaction between light and solid crystals from the viewpoint of refractive index (or dielectric function) based on Maxwell’s equations.

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.
Course materials are provided during class. Material may be provided via T2SCHOLA.
Students' understanding will be assessed by mini-exercises and reports.
