Abstract
A fusible link includes a current collector element, a battery cell conductor pad, and at least one fusible conductor connecting the current collector element and the battery cell conductor pad. The current collector element can be a current collector conductor pad, a current collector conductor pad and a current collector plate, or a fuse sheet. A battery cell has an anode electrode and a cathode electrode, a separate fusible link is coupled to at least one of the battery cell electrodes. The battery cell conductor pad is electrically and mechanically attached to each battery cell electrode. The fusible conductor opens under excessive current flow, and has sufficient service loop length to allow relative in-plane and out-of-plane motions between the battery cell electrode and the current collector element. The fusible links can be applied to each of a plurality of battery cells included in a battery pack.
