Abstract: Provided are methods and devices for storing and generating oxygen from a low temperature oxygen generating liquid. The oxygen storage method may use lithium chlorate plus water to store oxygen wherein all solids that may be present enter solution for delivery as a liquid to a reaction vessel. The oxygen production method may be a batch process with steps to heat the liquid, boil out the water, thermally decompose the lithium chlorate and then rinse out the remaining product. The apparatus for oxygen generation may use multiple reaction vessels operating sequentially to produce a continuous flow of oxygen with a rinse step in a separate area from the heat application area to remove end product solid. The device for oxygen storage includes a storage vessel and is configured to heat the oxygen generating liquid using waste heat present in the rinse liquid.
