Abstract
Electrochemical energy storage devices such as electric double layer capacitors include a flexible metal contact current collector establishing electrical contact with a conductive housing at numerous contact points. 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.
