Peking University, August 13, 2025: In a significant leap toward next-generation lithium battery design, researchers from the School of Materials Science and Engineering at Peking University, led by Professor Xia Dingguo, have discovered a previously unknown anionic redox mechanism in an amorphous Li-V-O-F cathode featuring tetrahedral coordination. Published in Nature Materials under the title “An amorphous Li-V-O-F cathode with tetrahedral coordination and O–O formal redox at low voltage”, the study demonstrates exceptional electrochemical performance and stability, surpassing the limitations of conventional crystalline cathodes and expanding the known boundaries of anionic redox chemistry.

Researchers at USC Viterbi School of Engineering have developed Allegro-FM, a groundbreaking AI model that can simulate the behavior of billions of atoms simultaneously.

The United States was the world’s largest source of carbon emissions for more than a century. In a new analysis, researchers document the changing trends in U.S. carbon emissions from the late 19th century to the early 21st century, focusing on emissions from fossil fuels and industry. They discuss the main factors that contributed to the rollercoaster of changes in historical carbon emissions. The authors close by offering lessons from the U.S. experience for developing countries.
