Abstract
The present invention provides an aluminum electrolytic capacitor having a cathode, an anode and an improved spacer comprised of polymeric nanofibers. The nanofiber spacer offers low ionic resistance, desirable barrier properties and high electrolyte absorption. The use of the improved spacer results in devices having higher capacitance, lower ESR, less heat generation and improved capacitor manufacturing efficiency.
