| Abstract: |
| The concentration of Zn2+ of pretreatment solution, pretreatment temperature and pretreatment time were selected. The concentration of Zn2+ which had influence on the performance of etched foil of Al electrolytic capacitor were explored. The technology of aluminum electrolytic capacitor anodic foil was studied to add the aluminum area and gain high capacitance.The results show that temperature of pretreatment solution rises to 65℃ , concentration of Zn2+ 2× 10- 5 g/ L and treatment extends 120 seconds, capacitance reaches maximum. |
