A TU Graz scientist, Stefan Freunberger, investigated ageing processes in non-aqueous batteries and found an enzyme to lengthen battery life. It has long been known in biology that the excited oxygen molecule, singlet oxygen, is the main cause of aging in cells. To counter this, nature uses an enzyme called superoxide dismutase to eliminate superoxide […]

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 […]
