Researchers from the Department of Energy’s SLAC National Accelerator Laboratory (SLAC) and Stanford University have made the first clear, detailed images of the solid-electrolyte interphase (SEI) layer in the wet environment of a working Li-ion battery by using cryogenic electron microscopy (cryo-EM). Although formation of SEI is believed to be...
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.
US-based researchers found a way to revitalize rechargeable lithium batteries, potentially boosting the range of EVs and battery life in next-gen electronic devices.
Lithium metal batteries could store much more charge in a given space than today’s lithium-ion batteries, and the race is on to develop them for
Cryo-EM snapshots of the solid-electrolyte interphase, or SEI, reveal its natural swollen state and offer a new approach to lithium-metal battery design.
