ELECTROCHEMICAL ENERGY STORAGE DEVICE WITH FLEXIBLE METAL CONTACT CURRENT COLLECTOR AND METHODS OF MANUFACTURE

摘要

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
