Battery swelled due to wrong tape?!

I replaced a screen and frame on an S8 Plus in October/November last year. Now the battery has swollen and my customer went to the store where he bought it and handed it in there. They sent it to their repair shop. The said that it had been repaired by someone incompetent, apparent in that the tape used isn't esd safe and not in line with the devices service standards or something along those lines.

Question: is this just bogus or is there something to it? Can the use of double sided tape (the kind you can use to fasten screens (now I use glue for that) cause the battery to swell?
