Should I be concerned about this mildly spicy pillow?

I only ask because the bulging seems slight enough that I'm not 100% certain that's not just how the battery is supposed to look.
This is inside a Lenovo ideapad flex 4. I only opened it to replace the hard drive.
Yes, that is a concern. Pictures of a new battery shows it to normally be flat or slightly indented in that area.
