摘要: An ultracapacitor that contains at least one electrochemical cell is provided. The cell includes a first electrode that contains a first carbonaceous coating (e.g., activated carbon particles) electrically coupled to a first current collector, a second electrode that contains a second carbonaceous coating (e.g., activated carbon particles) electrically coupled to a second current collector, an aqueous electrolyte in ionic contact with the first electrode and the second electrode and that contains a polyprotic acid (e.g., sulfuric acid), and a separator that is positioned between the first and second electrodes. Through selective control over the particular nature of the materials used to form the ultracapacitor, as well as the manner in which they are formed, a variety of beneficial properties may be achieved.

摘要: Provided is a method for manufacturing a power storage device in which a crystalline silicon layer including a whisker-like crystalline silicon region is formed as an active material layer over a current collector by a low-pressure CVD method in which heating is performed using a deposition gas containing silicon. The power storage device includes the current collector, a mixed layer formed over the current collector, and the crystalline silicon layer functioning as the active material layer formed over the mixed layer. The crystalline silicon layer includes a crystalline silicon region and a whisker-like crystalline silicon region including a plurality of protrusions which project over the crystalline silicon region. With the protrusions, the surface area of the crystalline silicon layer functioning as the active material layer can be increased.

摘要: An object of the present invention is to provide, at a low cost, a porous metal body that can be used in an electrode of a fuel cell and that has better corrosion resistance. The porous metal body has a three-dimensional mesh-like structure and contains nickel (Ni), tin (Sn), and chromium (Cr). A content ratio of the tin is 10% by mass or more and 25% by mass or less, and a content ratio of the chromium is 1% by mass or more and 10% by mass or less. On a cross section of a skeleton of the porous metal body, the porous metal body contains a solid solution phase of chromium, nickel, and tin. The solid solution phase contains a solid solution phase of chromium and trinickel tin (Ni3Sn), the solid solution phase having a chromium content ratio of 2% by mass or less, and does not contain a solid solution phase that is other than a solid solution phase of chromium and trinickel tin (Ni3Sn) and that has a chromium content ratio of less than 1.5% by mass.
