Working electrolyte for aluminium electrolytic capacitor and preparation method

Abstract

The invention relates to the technical field of electrolyte, in particular to working electrolyte for an aluminium electrolytic capacitor and a preparation method. The electrolyte comprises 75 percent to 85 percent of ethylene glycol, 1 percent to 5 percent of pure water, 2 percent to 8 percent of adipic acid, 2 percent to 8 percent of ammonium adipate, 0.1 percent to 2 percent of ammonium hypophosphite, 0.1 percent to 2 percent of meta-nitro acetophenone and 5 to 10 percent of polyethylene glycol (PEG). The working electrolyte has the beneficial effects that the working electrolyte has low cost, high oxidation efficiency, high electric conductivity and high spark voltage, can stably work for a long time under the high temperature condition, has service life of 3,000h at a temperature of 105 DEG C and can be widely applied to the fields of a switching power supply, a power adapter and the like.

AI Technical Summary

Benefits of technology

This technology has several benefits that make it more affordable than previous methods while also being able to withstand very harsh environments at temperatures above 90°C for longer periods without losing its effectiveness or causing damage during use.

Problems solved by technology

This patents discusses different types of technical problem addressed by this patented research group on electrical components like aluminized metal plasma capacitors (AML). These devices require good insulation properties at very high voltages while being able to maintain stable operating temperatures over many years without losing effectiveness caused by humidity. Additionally, these materials should have excellent resistance against corrosion when exposed to highly acid environments containing sulfurous compounds.
