The lab investigates how ions move in materials by studying their defects and stress.
AboutAbout the lab
Exploring material properties through defects and stress.
The Kimura Lab studies materials for solid state ionics, the field concerned with ions moving through solids.
The lab precisely measures the amount of defects that form in crystals and investigates how they change the properties of materials.
It also focuses on the stress applied to materials inside all-solid-state batteries, and explores whether material properties can be controlled by applying force.
Based on the scientific principles obtained, the lab designs material functions and develops materials, working toward environmentally friendly energy conversion devices.
On the lab's website, it is presented under the name "Amezawa Lab" (Solid State Ionics and Devices Research Field).
Key terms
- Solid state ionics
- The field that deals with the phenomenon of ions moving at high speed through solids. It is relevant to materials for fuel cells and batteries
- Nonstoichiometry
- The property by which the type and concentration of defects in a crystal change, causing the composition of the material to deviate from a fixed ratio
- Mixed conducting oxide
- An oxide that can conduct both electrons and ions. It is used as an electrode material for fuel cells, among other applications
ResearchResearch themes
In mixed conducting oxides, electronic and ionic conduction are closely tied to crystal defects such as oxygen vacancies. The lab investigates oxygen and cation nonstoichiometry, the effects of stress, and the incorporation of protons, in order to obtain the information needed to design energy conversion devices.
*Illustrative imageMeasuring How Easily Oxygen Is Released
Some mixed conducting oxides lose oxygen from the crystal and form vacancies depending on temperature and gas conditions. The lab studies the mechanism behind this oxygen nonstoichiometry and its effects on the function and strength of the material.
*Illustrative imageCation Nonstoichiometry and Material Properties
In oxides used for SOFC electrodes, cation defects have been thought to form hardly at all, but this means that even a slight change in composition greatly changes the cation activity. The lab prepares samples with controlled cation nonstoichiometry and measures how their properties change.
*Illustrative imageEffects of Stress on Battery Materials
In all-solid-state lithium-ion batteries, stress may arise internally from lattice mismatch between materials and from volume changes during charging and discharging. The lab places cells that mimic a cathode and an electrolyte under a relatively simple stress state by four-point bending, and evaluates changes in the chemical potential of Li from the electromotive force that is generated.
*Illustrative imageProtons Dissolving in Ceramics
Y-doped BaZrO3 is attracting attention as a candidate electrolyte for fuel cells that operate at low temperatures. Many aspects of how protons dissolve into this material remain unclear, so the lab precisely measures the amount dissolved using methods such as thermogravimetry and builds models based on defect chemistry.
