Chemistry of Materials

Critical to hydrogen’s widespread adoption as a clean energy source is its storage. Solid-state storage, where hydrogen is absorbed into metals, offers an alternative to high-pressure tanks. Yet hydrogen storage alloys face a trade-off between storage capacity and material stability. Tohoku University researchers discovered that magnetism governs this trade-off, and that by controlling the magnetic properties of alloys, it is possible to workaround this trade-off.

Solid electrolyte composed of nanoparticles embedded in an amorphous matrix shows high conductivity, formability, and electrochemical stability

Solid-state batteries are a safer option that can hold even more energy than current go-to lithium-ion versions, but effectively harnessing their structure-performance relationship has remained a complex barrier to better batteries. Now, however, researchers at Tohoku University’s Advanced Institute for Materials Research in Japan have developed a framework to predict how the structure of solid-state electrolytes can affect the performance of a battery.
