Composition for generating oxygen, oxygen generator, and method of generating oxygen

A composition for generating oxygen, comprising:

• an oxygen source, said oxygen source being potassium superoxide;
• an ionic liquid, said ionic liquid being a salt consisting of at least one cation and at most 100 cations, and at least one anion and at most 100 anions;
• a water-containing solution or a water-containing mixture, said water-containing solution containing a given amount of a further salt or a given amount of the further salt together with a given amount of an antifreeze, or the water-containing mixture contains a given amount of an antifreeze, to effectively lower a freezing point of said water-containing solution or of said water-containing mixture by at least 10° C. compared with a freezing point of the water;
• said further salt of said water-containing solution being an alkali metal hydroxide, an alkali metal hydroxide hydrate, an alkali metal chloride, an alkali metal chloride hydrate, a hydroxide with an organic cation, a hydrate of a hydroxide with an organic cation, or a mixture of at least two compounds selected from the group consisting of an alkali metal hydroxide, an alkali metal hydroxide hydrate, an alkali metal chloride, an alkali metal chloride hydrate, a hydroxide with an organic cation, and a hydrate of a hydroxide with an organic cation;
• and
• said antifreeze includes an alcohol or consists of an alcohol.
