The interior of the Apollo PLSS Diagram of the A7L PLSS and OPS, with interfaces to the astronaut and the Lunar Module cabin. The portable life support system used in the Apollo lunar landing missions used lithium hydroxide to remove the carbon dioxide from the breathing air, and circulated water in an open loop through a liquid-cooled garment, expelling the water into space, where it turned ...
Oxygen lost to side reactions can be replaced by ambient oxygen. [citation needed] Oi batteries feature lower energy density than lithium-ion batteries, and they operate at higher temperatures, can reach 200–400 °C (392–752 °F). [2]
The chalcogens (ore forming) (/ ˈ k æ l k ə dʒ ə n z / KAL-kə-jənz) are the chemical elements in group 16 of the periodic table. [1] This group is also known as the oxygen family. Group 16 consists of the elements oxygen (O), sulfur (S), selenium (Se), tellurium (Te), and the radioactive elements polonium (Po) and livermorium (Lv). [2]

For example, group 16 is also described as the "oxygen group" and as the "chalcogens". An exception is the " iron group ", which usually refers to group 8 , but in chemistry may also mean iron , cobalt , and nickel , or some other set of elements with similar chemical properties.
A 50 volt nickel–iron battery was the main D.C. power supply in the World War II German V-2 rocket, together with two 16 volt batteries which powered the four gyroscopes (turbine powered generators supplied A.C. for its magnetic amplifier driven servomechanisms).
