Should this hardware piece look like this?

In the image you can see the hardware part of the battery (I think) and it looks weird with all the white things. Is this normal, because the Mac was recently bought. This is a MacBook Air 2019.

Would be interesting to know what this is.

EDIT:

Added an image with circles to see the white things I am talking about. Also on those "bloated" metal things is some thin white layer, seems like the same thing like the other white stuff.

This looks normal.

• The circular white spots are moisture indicators, which turn red on contact with water. This is to inform a technician if the logic board has been in contact with water to possibly decline warranty cover for repairs.
• The ‘white dust’ on the edges are part of the production process.
