摘要:
Provided are interconnect circuits for interconnecting arrays of battery cells and methods of forming these interconnect circuits as well as connecting these circuits to the battery cells. An interconnect circuit may include a conductive layer and one or more insulating layers. The conductive layer may be patterned with openings defining contact pads, such that each pad is used for connecting to a different battery cell terminal. In some embodiments, each contact pad is attached to the rest of the conductive layer by a fusible link formed from the same conductive layer as the contact pad. The fusible link controls the current flow to and from this contact pad. The insulating layer is laminated to the conductive layer and provides support to the contacts pads. The insulating layer may also be patterned with openings, which allow forming electrical connections between the contact pads and cell terminals through the insulating layer.
摘要:
Provided are interconnect circuits for combined electrical and thermal energy transfer to devices connected to these circuits. Also provided are methods of fabricating such interconnect circuits. An interconnect circuit may include an electro-thermal conductor and at least one insulator providing support to different portions of the conductor with respect to each other. The insulator may include one or more openings for electrical connections and/or heat exchange with the electro-thermal conductor. The portions of the conductor may be electrically isolated from each other in the final circuit. Initially, these portions may be formed from the same conductive sheet, such as a metal foil having a thickness of at least about 50 micrometers. This thickness ensures sufficient thermal transfer in addition to providing excellent electrical conductance. In some embodiments, the conductor may include a surface coating to protect its base material from oxidation, enhancing electrical connections, and/or other purposes.
