摘要:
A capacitor includes an anode foil, a cathode foil, a conductive electrolyte, and a separator between the cathode foil and the anode foil. The conductive electrolyte fills between the cathode foil and the anode foil and contains butyrolactone. The separator includes an aromatic polyamide fiber material. The aromatic polyamide fiber material is non-woven and includes a para-aromatic-polyamide synthetic fiber. The separator has a thickness in a range of about 5 μm to about 20 μm and a density of greater than about 1.0 g/cm3.
