I tried it for much the same application, with little success.

Many, MANY moons ago, when I was working at Tandy Electronics, we sold
"solder tape" - which was almost as effective as wrapping an aluminium
chewing gum wrapper around the joint. By the sounds of it, this "wire glue"
is about as good.
If you're needing to solder directly to a button cell, just score the
surface extensively with a sharp blade and solder directly to it with a hot
iron and some fine rosin-cored solder; the joint will last at least as long
as the cell.
