This joint research project involves Japan Science and Technology Agency (JST), India's Department of Science and Technology (DST) and many Indian and Japanese academic institutions. The goal is to replace the liquid electrolyte in conventional batteries with solid lithium. Kalasalingam University's G. Hirankumar brought optimized cathode materials to Tohoku University's laboratories for three months of joint development. The one-micron thick, 5.2-volt batteries are expected to combine high energy density with thin film technology. These tiny batteries can supply currents of 1 mili-Ampere. Junichi Kawamura, director of Institute of Multidisciplinary Research for Advanced Materials (IMRAM) run by the Tohuku University, informs that these kind of batteries have already been employed in Japan in hybrid vehicle technologies. The thin-film battery market is expected to reach 11 billion USD by 2012, according to a 2006 report by Wintergreen Research."
