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.
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
Two-dimensional semiconductors have a big edge as far as creating next-generation electronics is concerned. They are quicker, stronger, and highly efficient. But, they are extremely hard to fabricate.
The Department of Energy is working to spur clean energy technology development through its "Energy Earthshots" initiatives, leveraging both its basic and applied science programs and the billions of dollars Congress has provided for demonstration projects.
