Abstract
A capacitor (100) includes first and second electrodes (102, 103) that each have an electroactive material (115, 120) disposed on a metallic substrate (105, 110). A solid electrolyte (125) including a polyacid is positioned between the first and second electrodes (102, 103). Polyacids are relatively low in cost, and their high ionic conductivity together with their thermal stability makes polyacids a viable alternative to solid polymer electrolytes.
