Electrolyte for very high voltage electrolytic capacitors |
摘要 |
An electrolyte comprising a polyester condensation product of 2-methyl-1,3-propane diol and boric acid; and further comprising dimethyl amino ethoxy ethanol in an amount to reduce the resistance of the electrolyte. The electrolyte may further comprise ortho-phosphoric acid and at least one substituted pyrrolidone or lactone, such as N-methyl-2-pyrrolidone, N-ethyl-2-pyrrolidone, N-hydroxy ethyl-2-pyrrolidone or 4-butyrolactone. The ortho-phosphoric acid prevents hydration of anodic aluminum oxide in contact with the solution. The pyrrolidone or lactone reduce the resistance of the electrolyte. The electrolyte may also comprise sodium silicate.
