The present invention relates to a power storage device impregnated with a mixture of phosphate oil and cholesterol. As a result of various experimental studies regarding the stability of a phosphate ester-impregnated capacitor, the inventor of the present invention has confirmed that the stability can be greatly improved by mixing cholesterol into the insulating oil. Next, the stability of the capacitor will be explained. A capacitor is a device that is operated by applying a voltage to a dielectric material, and various characteristics deteriorate during long-term voltage application. A capacitor with little deterioration can be said to have excellent stability. Structural deterioration of the capacitor includes deterioration of the dielectric material (including the impregnating agent) and deterioration of the electrode portion. Deterioration due to voltage application is due to temperature rise due to heat generation due to dielectric loss (tanδ),
Furthermore, this causes runaway deterioration such as an increase in dielectric loss, and deterioration such as gas generation from surrounding materials (dielectric, impregnating agent, etc.) due to micro discharge between electrodes. This is due to deterioration. There is also deterioration caused by the surrounding environment during use (due to temperature, humidity, etc.). Furthermore, there is also deterioration due to impurities such as moisture, and these effects also contribute to the deterioration of both the electrode and the dielectric. As described above, the deterioration of the capacitor is caused by various and complex factors, and the deterioration portion is caused by the material deterioration of the components. For this reason, it is often not possible to sufficiently evaluate the deterioration of a capacitor by tracking the capacitance, tan δ, and insulation resistance, which are the basic characteristics of a capacitor. As used in the evaluation of this example, the ratio (survival rate) of the capacitor remaining in a normally usable state without deterioration or destruction is an index of the stability of the capacitor. The above-mentioned phosphate ester oils include dioctyl phosphate, trioctyl phosphate, tributoxyethyl phosphate, tricresyl phosphate, tricylenyl phosphate, cresyl diphenyl phosphate, and diphenyl monoorthoxenyl. Phosphate etc. It was also confirmed that this effect was also exhibited in non-phosphate ester oils and phosphate ester mixed oils such as diarylethanes, fatty acid esters, and mineral oils. The following is the result after 500 hours of impregnating a capacitor element made of polypropylene film and aluminum foil with only the insulating oil and phosphate ester oil of the present invention, applying twice the rated voltage, and forcefully deteriorating it at 70°C. The remaining rate is shown in the table below.
