Breakthrough in Hydrogen Energy Storage
A new hydrogen battery can operate at temperatures four times lower than previous models, potentially leading to denser and longer-lasting EV batteries.
Researchers from Tokyo's Institute of Science have made a significant breakthrough in hydrogen energy storage, developing a battery that can store hydrogen at 194 °F (90 °C).
Being able to store hydrogen at 194 °F could dramatically change its use as an energy source.
This innovation uses magnesium hydride as the anode and hydrogen gas as the cathode, with a solid-state electrolyte featuring a crystal structure, allowing it to operate at much lower temperatures than current solid-state hydrogen storage methods, which require 572-752 F (300-400 degrees C).
This discovery could pave the way for future electric cars to ditch lithium-ion batteries in favor of more efficient hydrogen energy storage.
