Tohoku University Technology: Power storage device and material for its electrode: T12-175
Achieve energy density equivalent to lead battery by using only organic material! Safe, Low cost, and Long life
The applicability of quinone compound for both cathode and anode has been considered, aiming for low cost and safe energy storage material that does not contain rare or toxic element. However, even if quinone compound is supported on a porous material such as activated carbon, the quinone compound leaches out from the porous material, resulting in a short life span (that is to say poor cycle life) as an energy storage material. This invention solves the issue of cycle life. Consequently, we have demonstrated that the energy density of the new power storage device reaches the same level as a lead battery even though it is composed only of organic material.

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.
