Message from the CEO
Our company was founded to bring the innovative research developed in Professor Ishikawa’s laboratory at Kansai University to society. This includes the world-first discovery that certain ionic liquids can be used as electrolytes in lithium-ion batteries.
Ionic liquid batteries have demonstrated their suitability for space applications in satellites and rockets, and we continue to develop them jointly with partners involved in space operations. Their potential extends beyond space. Building on their ability to operate in high-temperature environments beyond conventional limits and their long service life, we are expanding their use in applications on Earth that require these capabilities. We have also successfully developed technologies that transform conventional electrode manufacturing processes, including additives that enable electrodes to be made from aqueous slurries regardless of the cathode material used.
Turning Original Ideas into Practical Applications
Turning Research into Value for Society
As a startup born out of Kansai University, we will help shape the future of energy by moving quickly and putting our ideas into action.
