BEFORE / AFTER

What changed from existing technology?

Existing technology

This study presents a new type of battery that can operate at very high voltages without breaking down.

This research

The study introduces a novel protective layer made of a fluoride solid electrolyte that allows the battery to operate at voltages above 5 volts.

03 · REALITY CHECK

Current stage: Basic research

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