Cryo-EM Reveals High-Resolution Images of Squishy Layer that is Key to Battery Performance
Scientists have made the first realistic close-ups of a plump, squishy layer called the solid-electrolyte interphase (SEI) that forms on lithium metal anodes as a result of chemical reactions with the electrolyte. Knowing what it really looks gives them a new way to improve next-gen battery design.
