Tokumasu Lab
Machine-translated · View original
A lab that computes flows in the nanoworld to contribute to battery technology.
AboutAbout the lab
Nanoscale flows, toward the next generation of battery technology.
The Tokumasu Lab studies flows that occur at the nanoscale from the perspective of how atoms and molecules behave.
Using supercomputers, the lab investigates the behavior of atoms and molecules through numerical simulation.
The knowledge gained is applied to next-generation industrial technologies, especially battery technology.
Research is organized into three groups: fuel cells, secondary batteries, and semiconductors.
Key terms
- Polymer electrolyte fuel cell
- A device that generates electricity from hydrogen and oxygen, using a polymer membrane as the electrolyte. It is used in home power systems and fuel cell vehicles.
- Secondary battery
- A battery that can be both charged and discharged. It is attracting attention as a battery that does not emit carbon dioxide or nitrogen oxides.
- Atomic layer deposition (ALD)
- A film deposition method used in semiconductor manufacturing that builds up a film one atomic layer at a time.

ResearchResearch themes
The lab analyzes flows at the nanoscale on supercomputers, focusing on the behavior of atoms and molecules. Divided into fuel cell, secondary battery, and semiconductor groups, it tackles the technical challenges of each.
*Illustrative imageFuel Cell Group
The components of polymer electrolyte fuel cells have nano- and microscale structures, and the transport phenomena inside them are difficult to observe experimentally. The lab investigates the transport mechanisms of protons, oxygen, and water through large-scale supercomputer calculations.
*Illustrative imageSecondary Battery Group
Secondary batteries, which can store electricity without emitting carbon dioxide or nitrogen oxides, are attracting attention as a way to address energy problems. The lab analyzes phenomena such as the transport of lithium ions within the electrolyte of all-solid-state lithium-ion batteries at the molecular level.
*Illustrative imageSemiconductor Group
Semiconductor film deposition requires atomic-layer precision, and methods such as CVD and ALD are used. The lab investigates deposition phenomena, in which diffusion and reaction are intricately intertwined, using reactive force field molecular dynamics and quantum chemistry calculations.
