摘要:
A package for an electrochemical double layer capacitor comprises 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 (h can ) and a diameter (d can ) such that an aspect ratio defined as h can /d can is in a range of 3.1 to 15. An electrode set adapted to be incorporated into the package can have an aspect ratio in a range of 3.1 to 15.

An after-treatment device for an automotive engine includes a substrate having a thermoelectric generation element disposed in an interior volume thereof. The substrate has a first end, a second end, and an outermost lateral dimension that defines an interior volume, and is configured to flow engine exhaust gas from the first end to the second end such that the flowing exhaust gas is in thermal contact with the thermoelectric generation element.
