Making Lithium Sulfur Batteries Last Longer
March 8, 2017 | Leave a Comment
University of Delaware researchers have demonstrated a new polysulfide entrapping strategy that greatly improves the cycle stability of Lithium Sulfide batteries. This may be significant as the energy density of lithium-sulfur (Li-S) batteries is five times higher than that of Lithium-Ion (Li-ion) batteries. Rechargeable Li-ion batteries are the power behind most modern portable electronics. But […]

Researchers at Caltech and the Berkeley Lab have in just two years nearly doubled the number of materials known to have potential for use in solar fuels. Using a new high-throughput method of identifying new materials, a team of researchers led by Caltech’s John Gregoire and Berkeley Lab’s Jeffrey Neaton and Qimin Yan have found […]

Pacific Northwest National Laboratory research shows adding a pinch of chemical additive to a lithium-metal battery’s electrolyte helps make rechargeable batteries that are stable, charge quickly, and go longer in between charges than lithium-ion batteries. New, early-stage research shows adding a small amount of the chemical lithium hexafluorophosphate to a dual-salt, carbonate solvent-based electrolyte can […]

Material Combines Incompatible Plastics For Recycling
March 1, 2017 | Leave a Comment
Cornell University’s Geoffrey Coats has developed a multiblock polymer that, when added in small measure to a mix of polyethylene and polypropylene creates a new and mechanically tough polymer. Coates collaborated with a group from the University of Minnesota and together the team’s work is detailed in the paper “Combining Polyethylene and Polypropylene: Enhanced Performance […]
