Teardown: A peek inside iPhone 6 Plus battery

Keywords:lithium-polymer  batteries  smartphone  iPhone 6 Plus  Apple 

The iPhone 6 Plus battery, weighing in at 43g, is not standing out from the trend line and does not seem to be special. But being Apple it is nonetheless interesting.

Our next item of interest is the BoM cost for the battery and to do this we need to know more about the battery's structure. Our teardown begins with the image below where we peel away the outer foil casing to expose a polymer film that envelopes the battery cells. This polymer film has been peeled away to expose the outer aluminum cathode collector layer shown in the next image.
