摘要：Porous separator is sandwiched between electrode films with attached currentcollector foil to obtain an electrode sheet. The electrode sheet is formed into a jellyrollfor use in a double layer capacitor. The jellyroll is inserted into a can through an openend to rest against the can's bottom. A collector plate is pressed against the jellyroll,
crunching current collector foil protruding from each end of the jellyroll. The bottomand the collector plate include indentations of reduced thickness. Laser is applied to theindentations to weld the foil on each end of the jellyroll to the bottom or collector plate.The laser application pattern, for example, a zigzag pattern, results in the total length oflaser welds along each indentation being considerably longer than the length of theindentation, reducing contact resistance between (1) the foil and the bottom, and (2) thefoil and the current collector.
