Astronauts complete the first spacewalk in series to upgrade the station's batteries

Two NASA astronauts replaced the batteries outside the International Space Station and completed the first in a series of five planned spacewalks devoted to upgrading the revolving laboratory's propulsion system. Expedition 61 flight engineers Christina Koch and Andrew Morgan worked 7 hours and 1 minute on Sunday (6 October) in the vacuum of space. Her extra-ordinary activities (EVA or spacewalk) …

A new coating could be the key to lighter lithium metal batteries

The problem with lithium-metal batteries is that they often develop small, tendril-like protrusions called dendrites. Over time, dendrites can pierce the protective film separating the positive and negative ends of the battery. And if the two sides interact with each other, there is a risk of a short circuit, which in turn can cause the entire energy cell to catch …
