We develop reliable battery materials at the large capacity that I made use of nano-plating technology of the Kiyokawa plating in as a cooperation study business of industry / a university / the administration of Fukui. We was able to raise the stability of the battery by having done special, uniform plating to electrode materials. We offer this sample to the battery maker by the end of 2008. And I aim at the practical use of less than 2 years.
