If the moisture content exceeds 95y, the resistance ratio of the aluminum electrolytic capacitor to the buccal low impedance will exceed 4, JC, and the resistance of the 2nd condition is 15%-95%. The phase water content is controlled by the total weight of the solvent, or one or one of the ethers, the ethyl acetate, the organic solvent, or the above, preferably: in the case of B: ethylene glycol-methyl ether. In an electrolyte with an alcohol or a household as an electrolyte, I water is the solvent's resistivity of the money salt compound, and the purpose of dissolving the water is to lower the resistivity of the liquid of the electrolyte, the value = In the case of :=, the more water added by L, the electrolysis of the electrolytic solvent, or the compound and water are maintained at a temperature for a long period of time, and it is difficult to place the performance at no load at 1 GG ° C or higher. For example, in the load test in which the mild reaction of the shoe produces a large amount of == pressure, the product volume at the same time drops sharply to 4 as the initial value. In the electrolyte of the present invention, a side% to 5% of an additive is added to the electrolyte of the present invention, and the additive is a water-repellent mixture, mainly containing a filling compound such as a mechanical acid or a nicotinic acid or Ammonium salt. Since the electrolyte contains a filler-containing compound, these Wei-containing compounds can inhibit the reaction with water, and the compound in the electrolytic solution can reduce the nitro group, so that it can absorb hydrogen gas from 1272627. However, when the content of the above waterproofing agent is less than 0.05% of the total weight, the protection effect on the anode foil and the cathode foil is not good. Therefore, the content of the waterproofing agent should be 0.05% or more, and generally the content is the total weight of the electrolyte. 0.05% - 5%. The waterproofing agent can ensure that the aluminum electrolytic capacitor does not hydrate when used for a long time at a high temperature, and also solves the problem that the high water content electrolyte easily corrodes the capacitor lead wire. The electrolyte composition of the above composition can maintain its respective functions and adhere well to the anode foil and the cathode foil, thereby suppressing the hydration reaction of the electrode foil and water, and preventing When the core is impregnated, the leads are corroded, thereby achieving the object to be achieved by the present invention.
