NASA often has fascinating science happening behind the scenes of its astronomical endeavors. Today, the space agency shared some details about a project to create batteries capable of withstanding extreme cold. The eventual goal is to use them for campaigns on the Moon, such as the future Artemis missions.
The lithium-ion batteries that power most electronics here on Earth are based on liquid electrolytes which can freeze at low temperatures, damaging the battery. And as you may have learned first-hand when your phone powers itself off in an overheated car, these types of batteries also won't work at very high temperatures. The moon can hit daytime highs of 212 degrees F (100 degrees C) while the nighttime lows at its southern pole plummet to as low as minus 328 degrees Fahrenheit (minus 200 Celsius), meaning current battery...
