Breakthrough Cryogenic Analysis Reveals True Nature of Battery Interfaces
Scientists have developed a cryogenic XPS technique that preserves battery interfaces in their pristine state. The method reveals a strong correlation between inorganic-rich SEI content and battery performance across multiple electrolyte formulations.
Revolutionary Cryogenic Technique Preserves Battery Interface Chemistry
Researchers at Stanford University have developed a breakthrough cryogenic X-ray photoelectron spectroscopy (cryo-XPS) method that maintains battery interfaces in their pristine state, according to recent reports published in Nature. The technique reportedly overcomes long-standing limitations of conventional room-temperature XPS analysis, which sources indicate can cause irreversible chemical changes and species volatilization under ultra-high vacuum conditions.
