A battery with 560 Watt-hours per kilogram, a stable long life, and no fires.  What’s not to like?  Researchers at Helmholtz Institute Ulm (HIU), founded by the Karlsruhe Institute of Technology (KIT) in cooperation with the University of Ulm, have come up with a dual anion, nickel-rich cathode, lithium-metal battery that, although in early stages of development, may point a way forward. Academic journal Joule reports, “High-energy batteries, in particular lithium batteries, are the key to achieve carbon-neutral mobility…. However, it is foreseen that a fully electrified mobility and transportation can only be achieved by the development of batteries employing lithium metal as the negative electrode (anode) while still granting long-term cycling performance and safety.”  Safety may be the deciding …

Medicine, STAT! Matternet is a U. S.-based company promoting its mission to, “Make access to goods as frictionless and universal as access to information.  Our products enable organizations around the world to build and operate drone logistics networks for transporting goods on demand, through the air, at a fraction of the time, cost and energy of any other transportation method used today. “ On March 27, it announced a collaboration with United Parcel Service (UPS) that delivered the first commercial medical payload at the WakeMed medical facility in North Carolina. Other non-commercial operations by Zipline, operating in Rwanda and Gambia; and  Swoop Aero, Ltd. and Wingcopter delivering vaccines in the South Pacific, are bringing “last mile” delivery of medical goods …
