Battery Tabs and Busbars: Specify the Connection
Identify where the part sits in the battery assembly and which materials it joins. Tabs and busbars need their own drawings, current profiles, joint requirements and inspection limits. Include the mating surfaces and production joining process in the RFQ.

| Decision | Battery Tab | Battery Busbar | Acceptance basis | Your input or result |
|---|---|---|---|---|
| Connection location | Electrode foil or cell terminal connection, as defined by the cell | Cell-to-cell, module or pack-terminal connection | Use the cell/pack drawing to identify which part is supplied. | |
| Material pair | Cell chemistry, polarity and terminal stack define permitted metals | Mating terminals and joint design define permitted metals | Review the allowed material pair before comparing resistance or mass. | |
| Drawing and tests | Tab section, weld area, forming and the cell process | Current path, joint layout, support and pack process | Specify current profile, joint strength, resistance and temperature-rise checks. |
