Coupling of cell to housing

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