Hydride ions (H⁻), known for their exceptionally low mass and high redox potential, have long intrigued scientists as potential charge carriers for next-generation electrochemical devices. Their unique properties suggest the possibility of batteries that are lighter, safer, and more energy-dense than current lithium-based technologies. Yet despite this promise, practical applications of hydride ions have been limited by one major challenge — the absence of electrolytes that c

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.
