Abstract

Theinvention provides a high molecular polymer, a preparation method thereof and an electrolyte containing the same. The high molecular polymer is shown in a formula (I), and is polymerized from monomeric isoprenol, methyl methacrylate, methacrylic acid, undecylenic acid and acrylic acid. The electrolyte uses the high molecular polymer shown in the formula (I) as a main solute. The 650V ultrahighvoltage capacitor prepared from the electrolyte meets the use requirements, and is more excellent in leakage current, loss and high temperature storage than similar capacitor products.

Description

technical field

[0001] The invention relates to the technical field of electrolytic solutions, in particular to a high molecular polymer and its application in the electrolytic solution of aluminum electrolytic capacitors. Background technique

[0002] Aluminum electrolytic capacitors are irreplaceable basic components in various electronic products. With the development of science and technology and the improvement of social needs, the requirements for aluminum electrolytic capacitors are getting higher and higher, making capacitors urgently move towards small size, long life, and durability. The mainstream direction of high temperature, high voltage resistance, high frequency ripple current resistance, low impedance, and low leakage current development.

[0003] As the cathode of the aluminum electrolytic capacitor, the electrolyte plays an important role in providing oxygen ions and repairing the anodic oxide film, and determines the working temperature range, rated volta...
