PREPARATION OF CAPACITOR ELECTRODES |
摘要 |
PREPARATION OF CAPACITOR ELECTRODES Aluminum capacitor foil which has been etched for low-voltage applications is rendered usable in intermediate to high voltage capacitors by anodizing the foil in two-stages: first a low voltage stage in an adipate electrolyte, and then a higher voltage stage in a borate electrolyte. The fine etch structure of the low-voltage etch is thereby not plugged in the second or higher voltage formation stage, whereby the foil is suitable for intermediate to high-voltage capacitor use. |
