Ihara-Manzhos Lab
Machine-translated · View original
The lab approaches energy conversion scientifically and develops it into devices and systems.

AboutAbout the lab
Making a science of energy conversion.
The Ihara-Manzhos Lab studies the chemistry and engineering of energy conversion.
Targeting electrochemical devices such as fuel cells, water electrolysis cells, and carbon-air secondary batteries, the lab covers everything from developing new materials and elucidating the mechanisms of reactions at electrodes to fabricating and evaluating devices.
It develops data science methods and integrates them into an intelligent energy system called Ene-Swallow.
Since 2021, a faculty member specializing in quantum chemical calculations and machine learning has joined, and the lab advances its research through both computation and experiment.
Key terms
- Solid oxide fuel cell
- A fuel cell that uses a ceramic electrolyte and operates at high temperature. It can use fuels other than hydrogen.
- Density functional theory
- A representative quantum chemical method that calculates the properties of materials from the behavior of electrons. Also called DFT.
- Energy materials informatics
- An approach that analyzes materials data with information science methods and uses the results to develop energy materials.

ResearchResearch themes
Toward carbon neutrality, the lab clarifies the fundamental mechanisms of energy conversion and develops them into devices and systems. Building on chemistry, it takes a comprehensive approach to research and development that makes use of information science and computing.
*Illustrative imageCarbon-air secondary batteries
The lab develops carbon-air secondary battery (CASB) systems that use carbon and air. It also works broadly on solid oxide fuel cells, developing electrodes suited to each fuel, new power generation methods, and electrolyte materials.
*Illustrative imageIntelligent energy systems
The lab conducts design, development, and scenario studies of energy systems. It has designed the Environmental Energy Innovation Building and developed Ene-Swallow, a system that manages smart grids.
*Illustrative imageComputational chemistry
Using density functional theory and molecular dynamics, the lab calculates the structures of materials and properties such as adsorption and mechanical properties. It also develops the computational methods themselves, such as machine-learning-enhanced orbital-free DFT, so that phenomena at larger scales can be handled.
