A study published in Optical Materials: Xoutlineshow ambient gamma radiation can be harvested to generate electricity for microelectronics.
The prototype battery, measuring just four cubic centimeters, achieves this by combining scintillator crystals with solar cells.
Researchers tested its effectiveness using two major fission products from spent nuclear fuel: cesium-137 and cobalt-60.
Experiments at Ohio State’s nuclear reactor laboratory yielded promising results.
The study also found that the shape and size of the scintillator crystals significantly influence electrical output.
Despite promising results, scaling up the technology presents challenges, primarily related to manufacturing costs.
Still, Oksuz remains optimistic about the future of nuclear-powered batteries.
“The nuclear battery concept is very promising.
