Business overview
 We are developing our ion-conductive polymer business within the sector of solid-electrolytelithium-ion secondary batteries. By producing and developing applications for a wide range ofsecondary battery materials, we established "ICP-m" (ion-conductive polymer matrix) systemtechnology and finalized the fundamental production technology for SE-ICP-m solid-electrolyte lithium-ion batteries in preparation for the construction of a semi-commercialplant. Furthermore, we have established a business program to drive the expansion ofcommercial production for SE-ICP-m solid-electrolyte lithium-ion batteries by licensing thissystem technology to the global market.
Paid-in Capital
 　50 million yen
place of business
 　Kyoto Office (Headquarters), Shiga Facility (Factory)

At the Annual General Meeting of Shareholders held on November 21, 2025,
Tsutomu Sada was appointed as Representative Director and has assumed the position.
We plan to announce our future management vision and objectives in due course.
In particular, we have launched sales of thermal-transfer conductive polymers
and are expanding their market application across various materials.
　Basic philosophy
Providing high-quality materials is the foundation for developing innovative technologies.
Leveraging our past experience, we are committed to doing our utmost to deliver
high-quality materials to our customers.

2020
 Steadily Advancing Technological Innovation Verifying Results
Amid the spread of COVID-19, we have leveraged remote work and other measures to overcome technical challenges one by one to the fullest extent possible, despite certainlimitations.
A major achievement has been the development of cell technology utilizing an ionic liquid-based electrolyte for high-voltage applications in next-generation lithium-ion batteries (LIBs).
Furthermore, we successfully established technology for bulk cathodes incorporating oxide-based materials (Garnet and NASICON) for solid-state LIBs. In particular, the successful development
of a medium-sized flat cell featuring a lithium metal foil anode and copper foil current collector represents a significant milestone that paves the way for future large-scale applications.
We have successfully achieved these technical development milestones by persevering through the constraints imposed on our R&D activities during thepandemic.
