As mentioned above, the key is to scale into the billions ... If we warmed Mars to Earth’s temperature, it’s atmosphere would lose oxygen and nitrogen more quickly than it already does.

The thin Martian atmosphere is 96% carbon dioxide, which isn’t much help to oxygen-breathing humans ... This would suggest that a full-scale system, designed to run continuously, could do ...

which produces oxygen from the Martian carbon dioxide atmosphere. The 10-person team at Noon Energy has since developed a battery that stores energy in carbon and oxygen using “nature-based ...
