Dear all,
I would like to weld 2 lithium battery cells together using spot welder. I understand that it's common using nickle tab on this purpose. The nickle tab dimension is about 0.5cm x 3cm.
My question is: can I replace nickle with aluminium or copper or other material since nickle cost me alot and it's hard to find them here? My concern if I don't use nickle, they will have lower performance and/or won't have a longer life. Please advice.
Many thanks!
Andre
