Energy Chemistry Lab
Machine-translated · View original
A lab that uses chemistry to store electricity, from battery materials to battery design.
AboutAbout the lab
New batteries, from chemistry
The Energy Chemistry Lab studies new substances, devices, and systems for converting, storing, and using electrical and chemical energy.
Its foundations are physical chemistry, inorganic chemistry, and electrochemistry.
The lab works on electrolyte and electrode materials for secondary batteries, battery design and analysis, new ionic liquids, and functional fluorine compounds.
Key terms
- Secondary battery
- A battery that can be recharged and used repeatedly, such as a lithium-ion battery
- Electrolyte
- A liquid inside a battery through which ions move between the positive and negative electrodes
- Ionic liquid
- A substance made up only of cations and anions that is liquid even around room temperature. It is hard to burn and slow to evaporate

*Illustrative imageElectrolyte and electrode materials for secondary batteries
Large secondary batteries need new materials built around safety, abundant resources, and sustainability. The lab develops a variety of electrolyte and electrode materials, aiming for efficient and long-lasting lithium-ion batteries, sodium-ion batteries, and metal batteries.
*Illustrative imageDesigning and analyzing batteries
New batteries need new designs suited to how they are used, and accurately knowing their performance requires appropriate measurement methods. Through practical battery design and advanced measurement, the lab develops various batteries suited to their applications.
*Illustrative imageNew ionic liquids as electrolytes
The lab uses ionic liquids, which are hard to burn and slow to evaporate, as electrolytes. Especially in batteries operated at elevated temperatures, it draws out the full potential of electrode materials and improves battery performance. It also works on synthesizing new ionic liquids and analyzing their structures.
*Illustrative imageCreating functional fluorine compounds
Fluorine has high electronegativity and produces bonds and functions that other elements do not. Drawing on its techniques for safely handling inorganic fluorine compounds, which are difficult to work with, the lab synthesizes functional fluorine compounds through new molecular design and analyzes their structures.
