The paper that goes around the bottom of the battery (?) is coming up on one side.
If you add additional thickness, you may end up breaking the battery case clamp. The battery has an insulated plastic case. There is no need to add anything else.You could always glue a piece of heavy paper in the bare spot for safety.
Maybe there are two pieces of paper, one on each side.There is no paper on the bottom of the battery. Only the plastic case with 3 contacts. I see no paper in the battery case either, just a couple of labels.
I have three of the large batteries. There is no paper on the bottom of any of them and the only thing on top is the label. If the label came off of the metal top of the battery, it would only come in contact with the foam pads on the plastic battery case cover and not cause any problems.Maybe there are two pieces of paper, one on each side.
Did this battery possibly get wet or stored in high humidity?
Thanks.That was more of a curiosity question.
Who knows what happened but it seems like the sticky side of the skin is failing or was not proper when it was applied.
I'd use it but with a close eye for a while and watch for more coming loose or signs of chemical leakage coming out between the white looking side and the part it stuck onto.
When I said 'not proper' before, I meant if maybe tooling oils or something with manufacturing may have gotten on the sticky surface which would cause it to not stick very well. Even oils from people's hands if these cells are made by hand for that stage.
I would not tug on it!Thanks. The battery seems ok, but what if the film comes all the way out?
"Is the film so loose that you are thinking it may just fall out?" No.I would not tug on it!

If not, try the small piece of scotch tape and see if that holds.
Without dissecting one of these batteries, I have no idea if there are more protective layers under what's seen in your picture.
If what you see is the only layer, that's a pretty poor design but also nothing I've not seen before. I think it all boils down into how much research and money went into the design.
If the film really does seem to be walking its way out more and more on its own each time you check it, then something is probably causing that and that may not be good. I'm thinking a chemical leak causing the film's glue to break down and that's pushing the film out.
If that stuff comes out more, look and if you see any signs of liquid on the film itself or you start seeing metal objects under what the film covered.
If so, I'd stop using it right away and follow the rule about getting it out of your home and inside a metal container!
Have you noticed any odd odors when handling this battery? Leaking Lithium cells will sometimes put off an odd chemical type odor which would probably be an indication something is leaking. In this case, I'd also stop using it and get it outside in a metal container or something so it does not catch your home on fire!
In that case, just play it safe and check on it by eye once in a while for any changes."Is the film so loose that you are thinking it may just fall out?" No.
"Have you noticed any odd odors when handling this battery? " No.
