So my basic question is if the cell is already Al to Steel
internally, might it be better to go Al to Steel to Al (that last Al
being my intercell connectors) than to do Al to Steel to Cu (which
would be copper intercell connectors)?
What little I know about metallurgy tells me that attaching steel to
aluminum is a bad idea. Maybe it can be done right by experts with
special techniques. Others who are knowledgeable about such things may
have more data with references.
But it's something that would normally be avoided. Just because the
Chinese did it does not make it good practice (they favor cheap, not
good). Certainly, for connections outside the cell in the "real world"
of water, oxygen, dirt, corrosion, etc. I would definitely avoid it.
If you insist on doing this anyway, then you should plan to measure the
actual resistance of each and every connection.
