The invention discloses an aluminum electrolytic capacitor paper, the raw material of which comprises the following components in parts by weight: 50-95 parts of insulating wood pulp fibers; and 5-50 parts of viscose fibers. The invention adopts insulating wood pulp fiber and viscose fiber, and by controlling the proportion of the two, the two can act synergistically, and the viscose fiber is dispersed in the electrolytic paper to form a rich, small and uniform void structure. The electrolytic paper of this structure A sufficient amount of electrolyte can be absorbed in the capacitor, and the resulting capacitor has low impedance and low loss, which can significantly improve the electrical performance of the aluminum electrolytic capacitor and prolong its service life. |
