Who wouldn’t want both?  Researchers in Germany and America are making great inroads on lithium battery energy density, while  adding some hope that batteries may someday outlast the vehicle in which they are installed. Ulm, Germany, where the Berblinger Competition encourages economical flight, may be a resource for making such flight possible.  The Zentrum für Sonnenenergie- und WasserstoffForschung Baden-Württemberg (Centre for Solar Energy and Hydrogen Research Baden-Württemberg, ZSW), has announced what they claim to be world-beating cells in terms of cycle life. Dr. Margret Wohlfahrt-Mehrens, Head of the Accumulator Material Research Department in Ulm reports, “After 10,000 complete charging and discharging cycles with a complete charge and discharge cycle per hour (2 C), our lithium batteries still have more than …
