Abstract
A packaged reactive material includes a reactive material that is configured to increase in size when exposed to a predetermined gas, and an inert coating material surrounding a surface of the reactive material. The inert coating material is configured to allow the predetermined gas to diffuse through to the reactive material and has an elongation that will not accommodate expansion of the reactive material at full saturation of the predetermined gas.
Claims22
A packaged reactive material, comprising:
- a reactive material that is configured to increase in size when exposed to a predetermined gas;
- and
- an inert coating material surrounding a surface of the reactive material, the inert coating material configured to allow the predetermined gas to diffuse through to the reactive material and having an elongation that will not accommodate expansion of the reactive material at full saturation of the predetermined gas.
A method for packaging a reactive material, comprising:
- selecting an inert coating material that is configured to allow a predetermined gas to diffuse therethrough and has an elongation that will not accommodate expansion of the reactive material at full saturation of the predetermined gas;
- dissolving the selected inert coating material in a non-reactive organic or inorganic solvent to form an inert coating material solution;
- coating a surface of a reactive material with the inert coating material solution;
- and
- allowing the non-reactive solvent to evaporate, thereby forming an inert coating material layer on the surface of the reactive material.
A hydrogen storage packaged reactive material, comprising:
- a reactive material that is configured to increase in size when hydrogenated;
- and
- at least one inert coating material surrounding a surface of the reactive material, the inert coating material configured to allow hydrogen to diffuse through to the reactive material and having an elongation that will not accommodate expansion of the reactive material at full hydrogenation.
