Researchers at Yonsei University led by Professor Yoon Seok Jung have created a fluoride-based solid electrolyte that shatters the 4-volt ceiling for all-solid-state batteries. The innovation enables safe operation beyond 5 volts and record-high capacity, marking a paradigm shift for electric vehicles and renewable energy storage.

Chinese researchers have achieved a breakthrough that sounds like science fiction – a solid-state battery that bends 20,000 times without breaking. This innovation solves critical problems in energy storage and could revolutionize wearable tech, flexible smartphones, and electric vehicles with 86% higher energy density.
