Battery System Research Group

The "New Battery Creation Studio", which is a hub for various electrochemical processes in the Battery System Research Group, has four technologies that have been nurtured over the years particularly in nickel-metal hydride batteries, lithium-ion batteries and fuel cells. 1. Material development and combination technology: we develop new materials based on various synthetic techniques, and draw out excellent electrochemical properties based on the ‘mystery’ that comes along upon the combination of new materials with the existing ones. 2. New battery fabrication technologies: through a judicious choice of both electrodes and electrolytes, we construct unique and novel battery systems suitable for applications that demand high-capacity batteries, all-solid-state batteries and so forth. 3. Performance evaluation and analytical technologies: we use numerous electrochemical evaluation techniques such as galvanostatic (dis)charge tests and impedance measurements to thoroughly investigate the performance of various types of batteries. 4. Safety evaluation technology: we develop safer battery configurations through the analysis of practical batteries using various techniques such as calorimetry and overcharge / internal short-circuit tests.

Pertaining to practical battery technologies prominently developed by industries, we take full advantage of our studio to create new potential technologies that fuses with the variety of technologies available at AIST. Through empirical research of various types of batteries, we strive to create new technologies and promote practical battery applications that will culminate in the development of batteries not only displaying higher capacity and higher power, but also with improved safety, reliability and of lower production costs.
