A wet electrolytic capacitor that includes a plurality of anodes, cathode, and working electrolyte that is disposed in electrical contact with the anodes and current collector is provided. Any number of anodes may generally be employed, such as from 2 to 40, in some embodiments from 3 to 30, and in some embodiments, from 4 to 20. The anodes are thin and typically have a thickness of about 1500 micrometers or less, in some embodiments about 1000 micrometers or less, and in some embodiments, from about 50 to about 500 micrometers. By employing a plurality of anodes that are relatively thin in nature, the resulting wet electrolytic capacitor is able to achieve excellent electrical properties. For example, the equivalent series resistance (“ESR”)—the extent that the capacitor acts like a resistor when charging and discharging in an electronic circuit—may be less than about 1500 milliohms, in some embodiments less than about 1000 milliohms, and in some embodiments, less than about 500 milliohms, measured with a 2-volt bias and 1-volt signal at a frequency of 1000 Hz.
