Diane Simard, Senior Vice President and a member of the Board of Directors for Bye Aerospace, sends your editor occasional news from that company.  The latest involves a collaboration with OXIS Energy in England to develop new Lithium-Sulfur battery cell technology that shows great, and (even better) near-term promise. Ready to start in September, the project will develop cells that will, ”Achieve the higher energy density required for such aircraft,” referring to Bye’s eFlyer 2 and eFlyer 4 light aircraft.  A big jump over currently available batteries, OXIS is now evaluating cells that produce 400 Watt-hours per kilogram, with a promised leap to 500 kW-hr by next year.  The best lithium-ion cells at the pack level available now manage 260 W-hr/kg. Huw W. Hampson-Jones, CEO of OXIS Energy, discusses his company’s unique approach to battery development and what this portends for future flight and general electric mobility.  Explaining OXIS’s applications, he adds, “Aviation is one of OXIS’ target markets, and …
