Indeed. It might work to start with, but the rubber adhesive on tape
will creep pretty soon and lose contact.

I have however bodged this in the past with superglue. You need to
glue two spots at the side (adding a springy metal bridge is easiest)
and make sure there's a glue-free contact in the middle. I don't
recommend this (tagged cells are as easy to buy as untagged), but it
did the job when needed and lasted the life of the cells.
