Development of innovative batteries for electric vehicle application-Overview of RISING Project-
Innovative Battery Research and Development Center
Rohm plaza, Nishikyo-ku, Kyoto, 615-8520 Japan
Background and Project objectives
<Background>
• Increasing demand for environmentally-benign electric vehicles (EVs)
• Current EVs with limited driving distance (ca. 100 km / charging) due to insufficient energy
of batteries, even with best lithium ion batteries (LIBs)
• Innovative batteries with high energy density (5 times of LIBs’) required
<Establishment of RISING project>
RISING (Research and Development Initiative for Scientific Innovation of New
Generation Batteries) Project founded in Kyoto University in 2009 under support of New
Energy and Industrial Technology Development Organization (NEDO) Japan
<Project target>
Development of technology to realize innovative
batteries with its performance much superior to LIBs
Establishment of novel analytical methods with society-
academia collaboration to understand and improve LIBs
Formation of interdisciplinary community for battery
