Abstract
Methods of fabricating the fusible link are directed to processing a multi-layer clad foil having a first layer suitable for forming a fusible link and a second layer suitable for forming one or more welding pads. In some embodiments, the first layer is an aluminum layer and the second layer is a nickel layer. A two-step etching process or a single step etching process is performed on the clad foil to form an etched clad foil having multiple tabs made of the second layer used as current collector conductor pads and battery cell conductor pads, and one or more tabs made of the first layer that form aluminum conductors. The aluminum conductors are shaped and sized to form aluminum fusible conductors during either the etching process or a subsequent stamping process. A single fusible link or an array of fusible links can be formed.
