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 […]






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 […]






University of Southern California (USC) scientists have developed an alteration to the lithium-sulfur battery that could make it more than competitive with the lithium-ion battery. The solution is for one of the biggest stumbling blocks to the next wave of rechargeable batteries – small enough for cellphones and powerful enough for cars. In a paper […]






Georgia Institute of Technology scientists have developed an anode material that enables sodium-ion batteries to perform at high capacity over hundreds of cycles. Lithium-ion batteries have become essential in everyday technology. But these power sources can explode under certain circumstances and are not ideal for grid-scale energy storage. Sodium-ion batteries are potentially a safer and […]






Massachusetts Institute of Technology (MIT) researchers’ new study unravels the properties of a promising new material for all solid state lithium ion batteries, which could be safer and longer-lasting than traditional batteries. The team at MIT probed the mechanical properties of a sulfide-based solid electrolyte material to determine its mechanical performance when incorporated into batteries. […]
