Abstract
Official abstract text for this publication.
To provide an electrode for an electricity storage device, which electrode employs a porous conductor having conductive nanostructures formed on its surface and makes it possible to provide a less expensive electricity storage device having a high discharge capacity and high charge/discharge cycle resistance.A porous conductor which is used as an electrode for an electricity storage device has a plurality of conductive nanostructures on a surface of the porous conductor.
First claim
Opening claim text (preview).
The invention claimed is: 1. A porous conductor comprising: a substrate; and a plurality of conductive nanostructures present on the substrate, wherein the substrate is a sintered metal fiber sheet that is formed with metal fibers such that a plurality of holes is formed among the metal fibers, wherein an average diameter of the holes is ranged from 1 to 300 μm, and the average diameter of the holes are calculated using at least fifty of the holes and referring to a longest diameter of each of the holes, wherein the conductive nanostructures include metal, wherein the shape of the conductive nanostructures is a dendrite, wherein the conductive nanostructures are directly attached to the metal fibers included in the metal fiber sheet. 2. The porous conductor according to claim 1 , wherein the metal fiber sheet includes a stainless steel fiber or a copper fiber. 3. The porous conductor according to claim 1 , wherein the metal is at least one or more of silver, copper, and cobalt. 4. An electricity storage device comprising the porous conductor according to claim 1 functioning as an electrode. 5. The electricity storage device according to claim 4 , wherein the electricity storage device is a redox capacitor.
