Verlauf von "What is the tape over the battery?" bearbeiten

I just had to change my battery on my Moto G4 Plus, and in the process accidentally tore up the black tape that was on the original battery.  I thought it wasn't a big deal, but I'm having second thoughts.  It's a black tape with a silver/metallic underside, and very thin.  What kind of tape is it, and is it important?
