International Classification:

H02N 11/00

US Classification:

310300

Abstract:

One nanostructured actuator embodiment includes an actuation region between electrical contacts. The actuation region includes an elastic matrix with embedded nanocomposite layered structures, which have inorganic material layers with pillared organic material structures between the inorganic material layers responsive to the surface acidity of the inorganic material layers. The elastic matrix allows transport of species for changing the surface acidity. A separator region is between the electrical contacts. A proton generation region capable of reversible electrochemical production and elimination of protons is provided, which may be a hydrogen storage material located on a side of the separator region opposite the actuation region, which may include metal hydride, or metal hydroxide. Alternatively, it may include an electrolytic solution and conductive particles within the elastic matrix for in situ electrochemical generation of an acid/base. The conductive particles may include carbon nanotubes, metal fibers, and/or metal nanoparticles.

Abstract:

In one embodiment, a solid state actuator is provided having a solid state lithium storage material and a solid state volume changing material having a metal capable of changing volume in response to lithium insertion and removal. A solid state lithium ion transport material is located between the lithium storage material and the volume changing material. A pair of electrodes are connected so as to be capable of providing an actuation voltage across the lithium storage material and the volume changing material. In some embodiments, the volume changing material has active material particles comprised of metal contained in an inactive matrix. The active material particles may be aligned so that when the active material particles expand the volume changing material expands substantially in one direction. In some embodiments the volume changing material is a metal alloy and the lithium transport material is a high stiffness material. In some embodiments, multiple actuators are stacked, interleaved, or pillared.

US Classification:

205357, 205358, 205549

Abstract:

A method for regenerating chemical hydrides from metal oxides and electrochemical cell for use in carrying out the method. The electrochemical cell has a cathode side with molten salt and a cathode, and an anode electrode side with an anode. The cathode side and the anode side are separated by an oxygen anion-conducting membrane. A metal oxide is placed in the molten salt of the cathode side and an electrical potential is applied to the cathode and anode while feeding hydrogen to the cathode electrode to effectuate conversion of the metal oxide to a metal hydride and feeding hydrogen to the anode to generate water and free electrons.

Abstract:

Compositions for hydrogen storage and methods of making such compositions employ an alloy that exhibits reversible formation/deformation of BH anions. The composition includes a ternary alloy including magnesium, boron and a metal and a metal hydride. The ternary alloy and the metal hydride are present in an amount sufficient to render the composition capable of hydrogen storage. The molar ratio of the metal to magnesium and boron in the alloy is such that the alloy exhibits reversible formation/deformation of BH anions. The hydrogen storage composition is prepared by combining magnesium, boron and a metal to prepare a ternary alloy and combining the ternary alloy with a metal hydride to form the hydrogen storage composition.
