Abstract

The development of high power and high capacity lithium secondary battery has been executed in a new strategic innovation scheme. This paper reports the significance of adopting the idea of interdisciplinary research to straightforward technology transfer from university, through AIST and battery company down to automobile company. A joint project of these organizations covering the upper stream science (at a university) and the down stream battery products (at a company) has been found a good scheme for rapid R&D when the university or AIST has innovative seeds. AIST has superiority in producing new technological seeds because of the interdisciplinary research between energy and nanotechnology as well as a wide spectrum of research fields covered by the institute. In this paper, an application of nanocrystalline electrode materials to high power battery is reported where the technology was successfully transferred to the commercial development of superior battery products.
