NASA's solid-state battery has a higher energy density than Tesla's batteries.
Guishi Automotive News — According to foreign media reports, NASA announced that its researchers are currently working on the SABERS (Solid-State Battery Efficiency and Safety Enhancement) project and have already achieved remarkable progress. They've developed a power battery with an energy density of up to 500 Wh/kg, more than double that of today's modern electric vehicle batteries.
Interestingly, NASA's research is part of its "Convergent Aeronautics Solutions" project, which falls under the broader field of aviation studies. However, the newly developed battery also has even wider-ranging applications. Compared to conventional batteries, this innovative approach reduces battery weight by 30–40% while doubling the energy density. In contrast, the 4680 "cookie" battery used in Tesla's Model Y currently boasts an energy density below 300 Wh/kg. Meanwhile, the upcoming standard-model Y vehicles will be equipped with CATL's M3P phosphate battery, which offers an energy density of just 160 Wh/kg.
SABERS' battery doesn’t come in individual packaging—instead, all the solid-state cells are stacked together inside a single box. This innovative design not only makes the battery lighter and more energy-dense than today’s electric vehicle batteries, but also allows the solid-state cells to fully leverage their inherent durability. NASA’s tests on this new type of solid-state battery revealed that it can withstand temperatures up to twice as high as those currently endured by lithium-ion batteries in EVs before they risk exploding or catching fire. As a result, this battery is ideally suited for use in aircraft. Currently, the NASA team is rigorously evaluating the battery’s sustained performance under conditions of even higher pressure and elevated temperatures. After all, enhancing battery safety remains a critical priority for advancing solid-state battery technology.
