Copper strips versus nickel strips on battery packs?
Copper is cheap and available, and it should remain cheap for the foreseeable future. Where it is most useful is in a small battery pack that has cells that are capable of putting out very high amps, because nickel has much more resistance. Nickel is affordable "right now". It is acceptable for a pack with a low total amp output.
Welding
Spot-welding strips and tabs onto batteries in order to make battery interconnections and larger battery pack assemblies is a common production technique. Typically, battery interconnections are made from nickel strips, often designed with splits and projections that are then resistance-welded using parallel gap or step welding methods.
