iFixit Apple Pencil teardown, there is no surprise because there is no Apple Product which iFixit didn't teardown. 

Apple Pencil is not easy to teardown, iFixit first removed the outer plastic casing of the Pencil to reveal the inner Metal casing. The tip has two emitters which determine the angle and the orientation of the Pencil's nib that adjusts the width of the stroke. iPad Pro contains a digitizer that determines the distance of the each emitter from the screen.

Next to a small cylindrical black and gold antenna they found Apple Pencil's tiny 0.329 Wh lithium-ion rechargeable battery that can run the Apple Pencil for 30 minutes with just 15 seconds of charge and can be fully charged in nearly 8 minutes to provide 12 hours of battery life. There is also a small ribbon like cable that connects the Apple Pencil's battery with its Lightning connector for charging.

On the other end of the battery is the Folded Logic Board of the Apple Pencil that weighs only one gram. The logic board contains more then five components shown below.

The logic board also contains a Cambridge Silicon Radio Qualcomm CSR1012A05 Bluetooth Smart IC which is not outlined in this image.

iFixit gave Apple Pencil the lowest repairability score 1 out of 10. But you can replace the Pencil nib and the cap. iFixit states there is no way getting into the Stylus without destroying it.The battery is also not replaceable.
