NASA’s batteries withstood extreme cold and heat. While liquid electrolytes freeze at certain temperatures, causing cracks in the casing and unwanted chemical changes in the battery, the solid-electrolyte batteries developed by NASA eliminate this problem. The solid electrolyte is ceramic or polymer. Thanks to this structure, the batteries can operate between -60°C and 80°C, and the solid structure provides protection even outside this range. The test was conducted under harsh conditions. In the tests, the battery cooled to -170°C was not damaged, and no capacity loss occurred when it was brought back to operating temperature with a small heater. The usage plan also includes the Moon. The batteries are planned to be used in extremely cold regions such as the permanently shadowed craters at the Moon’s south pole. Because they require less thermal management, the batteries also have applications on Earth.
Why it matters
In spacecraft, thermal control accounts for a significant portion of the weight and cost of energy systems; therefore, a battery that requires less thermal management means a direct reduction in design load. The development concerns lunar programs the most: the selection of the permanently shadowed craters at the south pole as target areas shows that temperature resistance is a mission requirement, not a laboratory curiosity. The search for applications on Earth as well indicates that the technology will not remain space-specific. On the other hand, the report does not provide information about the batteries’ energy density, charge cycle life, or production cost, nor does it mention any mission timeline. Since the information is based on Hackaday’s account, independent verification is not yet available.
