Because of the development of aluminum electrolytic capacitor, the electrolyte can not meet the requirement, so many new electrolytes h***e been produced to reduce the working temperature range of capacitor (for example, -55 ℃ -125 ℃). The principles of formulation of these new electrolytes are as follows: (1) mixing with two solvents to achieve complementarity; (2) using two weak acids to provide the two anionic groups required. 3 + alkali, such as organic amines, In order to adjust the ph value and flash voltage of the electrolyte and change its resistivity. 4 the additives to improve the characteristics of the electrolyte, such as preventing the formation of phosphoric acid or its salt for water cooperation in the aluminum oxide film, the dinitrobenzene that absorbs hydrogen, etc. Ethylene oxide that increases the flash voltage of the electrolyte.
