Lithium hydroxide was used to remove exhaled carbon dioxide from breathing gas during the Apollo mission.
Is there any research done how to recycle used lithium hydroxide on the Moon? Separating the carbon dioxide from the lithium and splitting it by electrolysis into carbon and oxygen. So both the oxygen and the lithium hydroxide may be reused?
There seems to be very little lithium found in lunar samples, so recycling is the only way to avoid importing it from Earth.
