Researchers have developed a battery that can convert nuclear energy into electricity via light emission, a new study suggests. Nuclear power plants, which generate about 20% of all electricity produced in the United States, produce almost no greenhouse gas emissions. However, these systems do create radioactive waste, which can be dangerous to human health and the environment. Safely disposing of this waste can be challenging. Using a combination of scintillator crystals, high-density materials that emit light when they absorb radiation, and solar cells, the team, led by researchers from The Ohio State University, demonstrated that ambient gamma radiation could be...

Korean researchers have developed advanced Ni-rich cathodes that improve all-solid-state battery performance, offering longer lifespans and greater energy efficiency. n an era where electronic devices and electric vehicles demand better battery performance, scientists are racing to develop batteries that last longer, charge faster, and store more energy. A promising solution lies in all-solid-state batteries (ASSBs), which could outperform traditional lithium-ion batteries in both efficiency and safety. At the heart of this innovation is the cathode active material (CAM), particularly those rich in nickel (Ni), which plays a crucial role in boosting battery performance. Role of Ni-rich cathodes ASSBs differ from...
