AI discovers the hidden signal of liquid-like ion flow in solid-state batteries

Solid-state batteries could be safer and more energy-dense than todays lithium-ion technology, but finding materials that allow ions to move quickly through solid electrolytes has been difficult. Researchers developed a machine learning pipeline that predicts Raman spectra and identifies a distinctive low-frequency signal linked to liquid-like ion motion inside crystals. This signal appears when rapid ion movement temporarily disrupts a crystals symmetry. The approach could dramatically speed up...
