Beschreibung
Zusammenfassung:	A package for an electrochemical double layer capacitor includes a housing defining an interior volume, the housing having an end wall, side walls, and an end cap configured to sealably engage with the side walls to enclose the interior volume, wherein the interior volume has a height (hcan) and a diameter (dcan) such that an aspect ratio defined as hcan/dcan is for an electrochemical double layer capacitor having a specific capacitance of at least 100 F. An electrode set adapted to be incorporated into the package can have an aspect ratio in a range of 3.1 to 15 and a specific capacitance of at least 100 F.
