ELECTROLYTE WITH CHELATING AGENT FOR ELECTROLYTIC ALUMINIUM CAPACITOR

摘要

An electrolyte having a high conductivity, an excellent high-temperature life characteristic and leading to improvement of the shelf characteristic of an aluminum electrolytic capacitor. At least one phosphate ion producing compound and a chelating agent are added using a solvent largely composed of water. Therefore, an aluminum electrolytic capacitor comprising such an electrolyte has a low impedance, an excellent high-temperature life characteristic, and an improved shelf characteristic.
