Lithium Batteries in Implants

[Satur9]

@rero_fox

Pacemakers use lithium iodine batteries. Is gas/swelling less of a risk in pacemakers because they are sealed in a metal housing, while a RFID implant cannot be made of metal for obvious reasons?

Yup, imported from another thread:

pacemakers use primary cell lithium iodide batteries that cannot be recharged, and the tiny amount of hyrdogen offgassing they do is accounted for in the construction of the device (they’re hermetically sealed and have metal casings that can withstand any pressure changes).
