Abstract

An apparatus including a body having dimensions suitable as an electrode component of an electrical storage device, the body having a fibrous form comprised of a moiety of the general formula:

(M_a)_x(Y_b)_y,

wherein M is one or more metals (i.e., a is greater than or equal to one) selected from Groups IV through IX of the Periodic Table of the Elements. Examples include, but are not limited to, ruthenium, iridium, and manganese. Y includes one or more heteroatoms (i.e., b is greater than or equal to one) selected from oxygen, nitrogen, carbon, and boron. Subscripts x and y represent the valence state of the cation and anion, respectively.

Claims

a body having dimensions suitable as an electrode component of an electrical storage device, the body having a fibrous form comprised of a moiety of the general formula;

(M_a)_x(Y_b)_y,

wherein M is a metal selected from at least one of Groups IV through IX of the Periodic Table of the Elements,

wherein a is greater than or equal to one,

wherein Y includes a heteroatom selected from one of oxygen, nitrogen, carbon, and boron,

wherein x is the valence state of the cation, and

wherein y is the valence state of the cation.

2. The apparatus of claim 1, wherein M is selected from the group consisting of molybdenum, tungsten, hafnium, zirconium, ruthium, iridium, and manganese.

3. The apparatus of claim 1, wherein the body comprises a plurality of fibers, each fiber comprising the moiety.

4. The apparatus of claim 3, wherein the plurality of fibers are combined in a weave.

5. An apparatus comprising:

a first electrode and a second electrode disposed in a cell; and

an electrolyte in fluid contact with the first and second electrode,

wherein each of the first electrode and the second electrode comprises a body having a fibrous form comprised of a moiety of the general formula;

(M_a)_x(Y_b)_y,

wherein M is a metal selected from at least one of Groups IV through IX of the Periodic Table of the Elements,

wherein a is greater than or equal to one,

wherein Y includes a heteroatom selected from one of oxygen, nitrogen, carbon, and boron,

wherein x is the valence state of the cation, and

wherein y is the valence state of the cation.

6. The apparatus of claim 5, wherein M is selected from the group consisting of molybdenum, tungsten, hafnium, zirconium, ruthium, iridium, and manganese.

7. The apparatus of claim 5, wherein the body comprises a plurality of fibers, each fiber comprising the moiety.

8. The apparatus of claim 7, wherein the plurality of fibers are combined in a weave.
