    摘要: High power density electrochemical capacitors may be pretreated by immersing the electrodes therefore in an alkaline solution. Thereafter the immersed electrode are subjected to high power pulses for brief periods of time. The pretreatment process forms an activated oxide layer on the electrode surface. The resulting device is capable of delivering high current pulses with enhanced discharge voltage.

    摘要: An electrochemical battery cell (10) including a zinc electrode (20), and may be fabricated with an electrolyte (50) system including an electrolyte active species and a modifier. The electrolyte active species is typically a metal hydroxide such as KOH or NaOH, while the modifier may be a porphine such as a metal porphine, and/or a polymeric material. The polymeric material may be, for example, a polyvinyl resin such as polyvinyl alcohol or polyvinyl acetate. The resulting electrolyte typically includes between 3 and 10 weight percent of the polyvinyl resin, 5 and 50 weight percent of the metal hydroxide, and between 1 PPM and 1 wt % of the modifier. Employing such an electrolyte in a cell including a zinc electrode results in an energy storage device having improved power density and substantially longer cycle life.

    摘要: An electrochemical capacitor device (10) including an anode (20) and a cathode (30) separated by a separator (40) and surrounded by an electrolyte (50). The anode (20) and cathode (30) is fabricated from a multi-valent, multiple oxidation state material. The material has a high, an intermediate, and a low oxidation state. In an initial condition, both the anode and cathode are in the intermediate oxidation state. During charging, one electrode will be oxidized to the higher states, while the other electrode will be reduced to the lower state. The processes are reversed during discharge.

    摘要: A method and apparatus for etchback profile control. The method includes performing a first etch through a first dielectric layer to form a first via and a second dielectric layer, filling the first via with a BARC material to form a first BARC layer, and performing a second etch on the first BARC layer to form a second BARC layer. The second etch has a first etch rate in a first peripheral region of the second BARC layer and a second etch rate in a first central region of the second BARC layer. The first peripheral region is located around a sidewall of the first via, and the first central region is located around a center of the first via. The first etch rate is larger than the second etch rate, and the first peripheral region is located higher than the first central region. A first top surface of the second BARC layer has substantially a first convex shape. Additionally, the method includes performing a third etch through a second dielectric layer to form a trench and a third BARC layer. The trench has a trench bottom surface, which is substantially free from any spike around a side surface of the third BARC layer. A second top surface of the third BARC layer has substantially a second convex shape. Moreover, the method includes removing the third BARC layer to form a second via.
