    Abstract: A battery interconnect may include a desired current capacity, integrated fusible links, and be manufacturable using cost effective techniques. In some embodiments, a battery interconnect includes a busbar and relatively thinner links. A busbar carries larger currents and accordingly its cross-sectional areas are relatively larger to reduce ohmic losses. A link carries a much smaller current, and a fusible link is configured to break the circuit when the current is above a threshold, thus requiring a relatively small cross-sectional area. These sometime disparate length scales are addressed using several techniques such as layering a busbar and a foil sheet and pressing portions of a busbar to form the links. The links can be affixed to a plurality of battery cells to connect the cells in parallel or series.
