Aluminum solid electrolytic capacitor and manufacturing method thereof

Abstract From the Canadian patent

An aluminum foil type of solid electrolytic capacitor has the distance between two foils in the capacitor element as determined by the thickness of a separator kept at a value between ten to sixty micrometers. A solid electrolyte is formed between the two foils by the thermal decomposition of an electrolytic solution impregnated into the capacitor element. A manganese dioxide electrolytic layer is formed between the electrode foils by thermally decomposing the electrolytic solution at a temperature between 200 and 260°C for a time between 20 and 40 minutes. The result is a capacitor with an improved impedance characteristic manufactured at low cost.
