University of Michigan (UM) researchers have designed a Kevlar barrier that goes between the anode and cathode electrodes of lithium ion batteries. The new battery technology should be able to prevent the kind of fires that grounded Boeing’s 787 Dreamliners in 2013. The barrier is made with nanofibers extracted from Kevlar, the tough material in […]

A Kansas State University (KSU) engineering team has discovered some of graphene oxide’s important properties that can improve sodium and lithium-ion flexible batteries. The KSU team is the first to show that a flexible paper composed entirely of graphene oxide sheets can charge and discharge with sodium-ions for more than 1,000 cycles. Sodium perchlorate salt […]

Over the past few days EEStor and the company holding better than 70 percent of its ownership, Zenncars, have released an independent test of it composition modified barium titanate ultracapacitor powders. The interest is increasing because Intertek Group Plc (“Intertek”) rigorously tested an extensive sampling of EEStor capacitor layers across multiple voltages (250vdc, 450vdc, 700vdc, […]

A research team at Helmholtz Institute Ulm (HIU) established by Karlsruhe Institute of Technology has now developed an electrolyte that may be used for the construction of magnesium-sulfur battery cells. The element magnesium is a another light metal offering very high theoretical battery capacity. Moreover magnesium is abundant in nature, it is non-toxic, and does […]

James Tour’s lab at Rice University has turned molybdenum disulfide’s two-dimensional form into a nanoporous film that can catalyze the production of hydrogen. The Rice University scientists also report the molybdenum disulfide film can be used for electrical energy storage in a capacitor. The versatile molybdenum disulfide compound classified as a dichalcogenide is inert along […]
