Previous attempts to make sulfur cathodes using bare sulfur or simply coated particles could not prevent the dramatic reduction of energy-storage capacity as the lithium-sulfur intermediate compounds (polysulfides) created during charging broke free and dissolved away.
SLAC programs explore the ultimate structure and dynamics of matter and the properties of energy, space and time -- at the smallest and largest scales, in the fastest processes and at the highest energies -- through robust scientific programs, excellent accelerator-based user facilities and valuable partnerships. Located in Menlo Park, California, SLAC is operated by Stanford University for the U.S. Department of Energy Office of Science.
