NASA says its sulfur selenium prototype battery has an energy density of 500 watt-hours per kilogram, which is about double that of conventional lithium-ion batteries.īut aircraft need enormous amounts of power to get off the ground. More energy storage is like having a larger bucket.
Viggiano says a battery is like a bucket that stores energy. The possibilities are pretty incredible.” “We’re starting to approach this new frontier of battery research that could do so much more than lithium-ion batteries can. “SABERS continues to exceed its goals,” said Rocco Viggiano, principal investigator for SABERS at NASA’s Glenn Research Center in Cleveland in a press release last year. NASA & SABERSįor years, NASA has been researching battery-powered flight as part of its Solid-state Architecture Batteries for Enhanced Rechargeability and Safety program.
The latest news from NASA should be of interest to both groups. It also fires the imagination of those who want to bring air taxis into commercial use. The promise of battery-powered flight is very much on the minds of airline executives who are under pressure to slash emissions from their flights. But batteries are heavy and bulky - two words that aeronautical engineers never want to hear.īut what if batteries had two or three times more power than today’s best lithium-ion batteries? And what if they also had no liquid or semi-liquid electrolyte inside that could burst into flames? “Fire” and “airplane” are two words that should never be used in the same sentence. As any EV advocate knows, vehicles powered by batteries and electricity are far more efficient than conventional cars powered by last century internal combustion technology.
It turns out, the “aeronautics” part of its mission includes advances in airplanes, and that means finding alternatives to conventional fuels that will leave fewer emissions behind during flight. We know it is responsible for Tang and space blankets, but what has it done for us lately? Most of us have little idea what NASA - the National Aeronautics and Space Administration - has been doing since the Apollo moon missions ended.
