NEW HYDROGEN BATTERY CAN OPERATE FOUR TIMES COLDER THAN BEFORE Scientists at Tokyo University of Science developed a hydrogen battery that works at 90 °C, four times colder than current systems. It uses magnesium hydride anodes, hydrogen gas cathodes, and a solid-state electrolyte. This lower temperature allows denser, longer-lasting EV batteries, matching lithium-ion efficiency without high-pressure storage. The study was published Sept. 18 in Science.(*Walter Bloomberg)
