Bosch Doubles Down on Solid-State Batteries

Bosch, the German electronics giant, is making a strong showing at the Frankfurt Motor Show (IAA), and showing off its solid-state Li-ion battery technology.  It recently acquired Seeo, Inc., an American startup that has been developing such a battery for several years, and will add Seeo’s research to its own expertise and exclusive patents. Encouragingly, the company says it will be able to double the energy density of Li-ion batteries while cutting prices by half.  Perhaps discouragingly, Bosch says this will take until 2020 to bring to production. Green Car Congress quotes Dr. Volkmar Denner, chairman of the board of management for Robert Bosch GmbH, claiming a breakthrough.  “Bosch is using its knowledge and considerable financial resources to achieve a …

Less Expensive Batteries May Lead to More Homebuilt Electric Airplanes

It came as somewhat of a shock that high-quality lithium battery prices could drop low enough to encourage electric aircraft developers an opportunity to “scrounge” in the style of the original home-built airplane builders.  Early aircraft “home-builders” often cannibalized war-surplus aircraft or wrecks of private planes for parts and materials that could be adapted into their own designs.  Ground power units (GPUs), for instance, became an early supply point for engine cores that could be converted to aircraft use – possible on “Experimental” homebuilts, although frowned upon by the FAA for factory-builts. Your editor thought at one point that auto wrecking yards might provide a source of used batteries for experimental electric airplanes, but the thought of all the internal …
