Abstract
928,033. Electrolytic capacitors; forming aluminium and tantalum. TELEGRAPH CONDENSER CO. Ltd. (Sprague Electric Co.). Oct. 10, 1960, No. 34605/60. Classes 37 and 41. In an electrolyte for an electrolytic capacitor the solvent constituent comprises either (1) an N-substituted amide of an organic acid, other than formic acid, having the general formula wherein R 1 and R 2 represent organic radicals and R 3 represents either hydrogen or an organic radical; or (2) a mixture of two or more such amides. Examples of such solvents are N-N-dimethylacetamide, N-ethylacetamide and N- methylpropionamide. The solute constituent of the electrolyte may be boric acid or a salt of boric acid; examples being a substituted ammonium pentaborate, such as tetra allyl ammonium borate, or cinnamyl triethyl ammonium borate. Capacitors using the electrolyte according to the invention may include anodes composed of valve metals such as aluminium or tantalum, and the electrolyte may be both a forming and a working electrolyte.
