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 …

Battery Prices and Lithium Futures

EV World has a weekly email update to which your editor subscribes.  Because they provide a collection of articles and opinions from different sources, one often comes away questioning trends and even facts – or sometimes the meaning of it all. This week, an article referenced from Green Car Reports says that EV batteries may already have fallen to $250 per kilowatt hour.  This would be a godsend for sales of battery-powered cars, because sticker prices would drop sharply.   The article quotes Wolfgang Bernhart, a partner at Rolan Berger Strategy Consultants, that battery prices are already much lower than previous predictions would have indicated, possibly as low as $250 per kilowatt hour.  His analysis credited economies of scale for this …
