A current collector assembly includes an electrically conductive layer with several tabs used to electrically couple with one or more battery cells. The tabs may connect to an interconnect of the electrically conductive layer by way of a fuse. Several fuses may include portions of difference sizes. For example, one portion of the fuse may be relatively longer and narrower, while another portion of the fuse may be shorter and wider. The narrower portion may be positioned between insulating layers of the current collector assembly, while the wider portion extends from the insulating layers. The wider portion of the fuse increases the likelihood of the fuse remaining intact when various forces are exerted on the fuse.
