BEFORE / AFTER

What changed from existing technology?

Existing technology

This study shows a solid-state battery that can be recharged many times at room temperature, using hydrogen ions to store and release energy.

This research

This is the first demonstration of a rechargeable all-solid-state hydride ion battery operating at room temperature.

03 · REALITY CHECK

Current stage: Basic research

Classified from the research published in Nature and its publicly reported validation. Manufacturing and revenue evidence require separate confirmation.
