Hydrogen storage nano-foil and method of manufacture

摘要

A hydrogen storage system using a coiled nano-foil hydride and methods for forming the hydrogen absorbing nano-foil coil without backing materials. Intercalation of hydrogen in metal hydrides allows for large amounts of hydrogen to be stored at atmospheric temperatures and pressures. Nano-films provide a large surface area for storage of hydrogen. Excessive heating of the system is avoided by use of a modified magnetron source, and the deposition rate is increased by employing stronger magnetic fields. The foil formed is capable of storage and of mechanical self-support without breakage and expansion up to 20% of its initial volume.
