The lab contributes to the SDGs with mysterious salts and common elements.

AboutAbout the lab
Creating the materials of the future from liquids made only of ions.
The Tsuda Lab conducts research based on liquid salts made up solely of ions (ionic liquids and molten salts), electrochemistry, and materials science.
It works on developing energy materials, energy storage devices, resource recycling processes, and analytical technologies that can contribute to achieving the SDGs.
To the three pillars of ionic liquids, electrochemistry, and materials science, the lab adds two keywords, low environmental impact and common elements, with the aim of creating materials and recycling technologies that support the future of humankind.
The lab keeps its rules to the necessary minimum and strives to provide research supervision that respects each individual's autonomy.
Key terms
- Ionic liquid
- A salt made up only of cations and anions that is liquid even at room temperature. It hardly evaporates and is hard to ignite.
- Electrochemistry
- The field that deals with chemical phenomena involving electrically charged particles such as electrons and ions.
- In situ observation
- Observing a reaction while it is taking place, without stopping it, using tools such as an electron microscope.

*Illustrative imageDevelopment of New Ionic Liquids
By designing the molecules of organic cations and controlling the structures of complex ions, the lab creates ionic liquids with targeted properties. It is working on developing new ionic liquids intended for use in the energy field.
*Illustrative imageOne-Pot Synthesis of Energy Materials
When an ionic liquid is used as the reaction medium, nanoparticles remain stable even without stabilizing agents. Simply adding a metal precursor to an ionic liquid and heating it produces metal or alloy nanoparticles, and if a carbon material is mixed in beforehand, even the supported material can be made in a single step.
*Illustrative imageIn Situ Observation of Electrochemical Reactions
Ionic liquids hardly evaporate and do not become electrically charged, so the inside of the liquid can be observed with an electron microscope without a sealed cell. The lab observes how the negative electrodes of next-generation secondary batteries, such as silicon, lithium, magnesium, and zinc, change during charging and discharging.
*Illustrative imageHigh-Purity Recycling of Aluminum
In repeatedly recycled aluminum, impurities such as silicon accumulate, and in the end it is discarded as scrap. Using aluminum chloride-based ionic liquids, the lab is developing an industrial process that purifies scrap to the level of virgin aluminum ingots using little electric power.
