Abstract:

Battery packs having electrically insulating material between conductive surfaces of electrical components are described herein. In some embodiments, a battery pack includes a battery cell with a first conductive surface, an electrically conductive member with a second conductive surface, and electrically insulating material positioned between the first and second conductive surfaces. The electrically insulating material has at least one passage that enables the first and second conductive surfaces to be electrically connected. For example, the passage in the electrically insulating material may be formed by, during, or as a result of a process in which the first and second conductive surfaces are attached, such as by a welding process that both ablates a portion of the electrically insulating material to form the through passage and that physically joins the first and second conductive surfaces, thereby creating an electrical connection therebetween.
