Abstract
Electrochemical energy storage devices such as electric double layer capacitors include flexible metal contact current collectors establishing electrical contact with a conductive housing and a conductive cover. The flexible current collector simplifies manufacturing of the device and avoids laser welding on the conductive housing. The manufacture devices are operable with a reduced direct current resistance by virtue of the flexible current collector.
