Scientists develop battery that converts nuclear energy into electricity via light emission
A new battery converts nuclear energy into electricity using light emission, offering potential for nuclear waste repurposing.
Researchers at Ohio State University have developed a battery that converts nuclear energy into electricity through light emission. Their innovative design utilizes high-density scintillator crystals and solar cells to transform gamma radiation from nuclear waste into electrical power, as noted in a study published in Optical Materials: X. Testing with fission byproducts cesium-137 and cobalt-60 showed the battery could produce nanowatt to microwatt levels of electricity.
The team led by Raymond Cao successfully tested the device at Ohio State's nuclear reactor, producing up to 1.5 microwatts with cobalt-60, enough to power small sensors. This development could revolutionize energy harnessing from nuclear waste, repurposing a traditionally hazardous material. Researchers believe these batteries could be valuable for nuclear waste sites, space, and deep-sea applications as they do not contain harmful radioactive materials.
Challenges remain, particularly in scaling the technology due to high manufacturing costs. Associate researcher Ibrahim Oksuz highlighted the potential for greater power output with scaled-up designs and larger scintillator crystals. Despite uncertainties, the researchers remain optimistic about the role nuclear-powered batteries could play in energy production and the sensors industry, emphasizing the need for continued research and development.
