(Phys.org) -- As their name suggests, Li-air batteries use air to operate, pulling out oxygen molecules to use in a porous, carbon-based cathode, while using lithium in the anode. Because using air means the battery doesn’t ...
Atmospheric oxygen facilitated the evolution and complexity of terrestrial organisms, including human beings, because it allowed nutrients to be used more efficiently by those organisms, which in turn were able to generate ...
