Problems solved by technology

In particular, choosing too many low-carbon chain dibasic acid salts will cause technical problems such as large leakage current of the capacitor, low voltage resistance and easy ignition, and the problem that ammonium sebacate is difficult to dissolve in the electrolyte

Embodiment 1 and Embodiment 2

[0048] This example provides the effect of the esterification rate of ammonium sebacate in the main solute on the performance of the high-voltage high-conductivity electrolyte.

[0049] The main solute used in the present invention is high-concentration ammonium sebacate-ethylene glycol solution, and ammonium salt cannot undergo esterification reaction with alcohol in general. However, in a solution system environment, ammonium salts are prone to ionization. When carboxylate ions combine with hydrogen ions, carboxyl groups are formed, which can undergo esterification reactions with hydroxyl groups in ethylene glycol. As the esterification reaction proceeds, the concentration of hydrogen ions decreases and the pH increases, and ammonium sebacate is a weak base salt. Under alkaline conditions, the generated ester is also prone to hydrolysis reaction, which is a reciprocal balance reaction. So what we need to explore is how much the reaction esterification degree is, which is co...

Embodiment 1

[0054] Example 1: 15 g of ammonium sebacate was added to 85 g of ethylene glycol, mixed and stirred, heated to 110° C., and kept for 2 hours for reaction. Cool down to about 60°C, and adjust the pH to 7-8 by introducing ammonia gas.

Embodiment 2

[0055] Example 2: 20 g of ammonium sebacate was added to 80 g of ethylene glycol, mixed and stirred, heated to 110° C., and kept for 2 hours for reaction. Cool down to about 60°C, and adjust the pH to 7-8 by introducing ammonia gas.

Abstract

The invention belongs to the technical field of electrolyte preparation, and particularly relates to a high-voltage and high-conductivity electrolyte and a preparation method and application thereof.The method comprises the steps of performing esterification reaction on ammonium sebacate and ethylene glycol, and preparing the electrolyte by taking a reaction product as a solute. By the method, the interference of other substances on the esterification reaction between the ammonium sebacate and the ethylene glycol due to direct addition of the ammonium sebacate is overcome, the problem of lowsolubility of the ammonium sebacate in the ethylene glycol is solved, the mass fraction of the ammonium sebacate in ethylene glycol can reach 15-20%, and the electrolyte obtains high conductivity. Moreover, the ammonium sebacate is relatively good in high-temperature resistance and high-voltage resistance, an electrolytic capacitor can have relatively low impedance due to preparation of the electrolyte, and thus, the high-voltage and high-conductivity electrolyte is longer in service lifetime and is safer. The preparation method is simple, the material is available, the process condition is easy to control, and industrial production is easy to implement.
