NASA’s Solid-state Architecture Batteries for Enhanced Rechargeability and Safety program (SABERS) has made significant breakthroughs in battery-powered flight research. A sulfur selenium prototype battery developed under the program boasts an impressive energy density of 500 watt-hours per kilogram, doubling that of traditional lithium-ion batteries.
Not only are these batteries more energy-efficient, but SABERS researchers have also discovered a method to enhance their discharge rate, making them ten times faster than when the research began. One of the major advantages of these sulfur selenium batteries is that they can be stacked without the need for casings, allowing for lighter weights and increased energy storage in a given space.
Moreover, these batteries have proven to be more resistant to high temperatures and less sensitive to changes in pressure. This durability opens up possibilities for reliable use in a range of aviation applications.
Although cost remains a significant factor, the potential benefits for airlines and air taxi companies are undeniable. By spreading the cost over thousands of flights, the investment in these advanced batteries may become financially viable for the aviation industry.
NASA’s involvement in battery-powered flight research is part of its broader mission to understand the dynamics of advanced air mobility. The agency aims to integrate air taxi services, package delivery, and emergency medical services into existing flight corridors. In collaboration with industry and community partners, as well as the Federal Aviation Administration (FAA), NASA envisions creating a safe, accessible, and affordable air transportation system that caters to various levels of ability.
By exploring design and operation options for aircraft and accommodating accessibility needs, NASA is laying the groundwork for a future where battery-powered flight becomes a reality. The progress made under SABERS is a significant step towards achieving this vision, offering promising prospects for a greener and more sustainable aviation industry.
