World's first water-based nuclear battery developed by Kwon’s research group at MU
World's first water-based nuclear battery was developed by Kwon’s research group at the University of Missouri.
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.
