Battery interconnects
First Claim
1. An interconnect for interconnecting a set of battery cells, the interconnect comprising:
- a conductor, comprising a first portion and a second portion, electrically isolated from the first portion,wherein the first portion comprises a first contact, a second contact, and a fuse, the fuse forming electrical connection between the first contact and the second contact and being monolithic with the first contact and the second contact, andwherein thicknesses of the first contact, the second contact, and the fuse are same;
a first insulator, adhered to the conductor and mechanically supporting the first portion and the second portion of the conductor relative to each other,wherein the first insulator comprises a first opening such that the fuse fully overlaps with the first opening;
a second insulator, adhered to the conductor and mechanically supporting the first portion and the second portion of the conductor relative to each other,wherein the second insulator comprises a second opening such that the fuse fully overlaps with the second opening, andwherein the conductor is positioned between the first insulator and the second insulator; and
a heat sink, adhered and thermally coupled to the second insulator such that the second insulator is disposed between the heat sink and the conductor and the conductor is electrically insulated from the heat sink.

Abstract
Provided are interconnects for interconnecting a set of battery cells, assemblies comprising these interconnects, methods of forming such interconnects, and methods of forming such assemblies. An interconnect includes a conductor comprising two portions electrically isolated from each other. At least one portion may include two contacts for connecting to battery cells and a fuse forming an electrical connection between these two contacts. The interconnect may also include an insulator adhered to the conductor and mechanically supporting the two portions of the conductor. The insulator may include an opening such that the fuse overlaps with this opening, and the opening does not interfere with operation of the fuse. In some embodiments, the fuse may not directly interface with any other structures. Furthermore, the interconnect may include a temporary substrate adhered to the insulator such that the insulator is disposed between the temporary substrate and the conductor.
