Researchers create tiny nuclear-powered battery thousands of times more efficient than predecessors

Chinese researchers have developed a highly efficient miniature nuclear battery, potentially 8,000 times more effective than previous versions. The device uses americium in a crystal to produce light, which is then converted to electricity by a photovoltaic cell. While the power output is very small, the battery could potentially last for decades. This breakthrough could lead to long-lasting power sources for small remote devices, including those used in deep space exploration.
