Promoting green innovation

To promote green innovation, AIST is developing technologies for increased use of alternative energy technologies, such as renewable energy sources that reduce greenhouse gas emissions (energy creation), high-density storage of energy (energy storage), highly efficient conversion and use of energy (energy saving), effective utilization of energy resources, and evaluation and reduction of environmental risks.


New Research Results

Development of SiC-based Next Generation Transistor Structures

AIST has developed 1.2 kV withstand voltage class vertical super junction (SJ) MOSFETs that use semiconductor SiC and achieved the world's lowest on-resistance for a SiC transistor. The developed SJ-MOSFETs were also demonstrated to have superior high temperature characteristics and dynamic characteristics.

Development of Oxide Cathode Materials for 4 V Class Potassium-Ion Batteries

AIST selected candidate compounds using crystal structure analysis and theoretical calculations, and has developed novel oxide cathode materials of 4 V class for potassium-ion batteries. Performance of the developed oxide materials vastly exceeds prior oxide materials. The materials hold promise for battery applications.

Open Innovation Laboratory

Since FY 2016, as a part of the “Open Innovation Arena concept” promoted by the Ministry of Economy, Trade and Industry (METI), AIST has created the concept of “open innovation laboratories” (OILs), collaborative research bases located on university campuses, and has been engaged in their provision. We are planning to establish more than ten OILs by FY 2020.

AIST will merge the basic research carried out at universities, etc. with AISTʼs goal-oriented basic research and applied technology development, and will promote bridging research and evelopment and industry by the establishment of OILs.

Cooperative Research Laboratories

In order to conduct research and development more closely related to strategies of companies, we have established collaborative research laboratories, bearing partner company names.

Partner companies provide their researchers and funding, and AIST provides research resources, such as its researchers, research facilities, and intellectual property. The loaned researchers of companies and AIST researchers jointly conduct research and development.

By setting up cooperative research laboratories, we will accelerate the commercialization of our goal-oriented basic research and application research with partner companies.
