World's first water-based nuclear battery developed by Kwon’s research group at MU

Sep 18, 2014 06:17 IST

World's first water-based nuclear battery was developed by Jae W. Kwon’s research group at the University of Missouri (MU). This research titled Plasmon-assisted radiolytic energy conversion in aqueous solutions was published in the journal Nature on 11 June 2014.

Highlights of the study
•    The battery can be used as a source of reliable energy in automobiles and space flight.
•    It uses a radioactive isotope called strontium-90 that boosts electro-chemical energy in a water-based solution.
•    A nano-structured titanium dioxide electrode with a platinum coating in the battery collects and converts energy into electrons.
•    Water acts as a shield and its efficiency is increased by the surface plasmons created in the battery.
•    The ionic solution is not easily frozen at very low temperatures. It can work in a wide variety of applications including car batteries and spacecrafts as well.
