Tohoku University Technology: Ultracapacitor materials and ultracapacitors: T18-089
Able to store more electricity by using amorphous titanium
In recent years, with the rapid development of high-performance IT products and electric vehicle batteries, the demand for small capacitors with high capacity having high function such as memory is increasing. Solid, non-toxic and inexpensive materials are required for such capacitors. However, solid-state electric double layer capacitors are not yet in use. In addition, amorphous titania and amorphous fluorine polymers with nano sized irregularities on their surfaces have been developed to create quantum size effect-based energy storage materials. However, amorphous titania-based energy storage materials have low electricity storage capacity. This invention is able to provide ultracapacitor materials and ultracapacitors capable to store a larger quantity of electricity using amorphous titania. This invention includes Ti and a valve metal and has a plurality of irregularities on its surface comprising an amorphous ultracapacitor material composed mainly of TiO6.

Company information
The revenue generated from technology transfer is reinvested as new research funding for universities and researchers, and is utilized to create further research outcomes. To ensure the smooth operation of this cycle, known as the "Intellectual Creation Cycle," we will vigorously promote technology transfer. The types of seeds we handle include patents, know-how, databases, and programs. We have established a collaborative framework by signing basic technology transfer agreements with the following universities (as of June 1, 2025): Tohoku University, Hirosaki University, Iwate University, Akita University, Fukushima University, Yamagata University, Tohoku Gakuin University, Iwate Medical University, Fukushima Medical University, Aizu University, Miyagi University, Hokkaido University, Muroran Institute of Technology, and Showa Medical University.
