No. The adhesive remains in the iPhone, so you do not need to add any extra. Also the space tolerances are so tight inside the iPhone, no adhesive is necessary, there is no place for the battery to move to. Just for information the adhesive Apple uses is the standard double sided adhesive Apple uses throughout the iPhone. The adhesive is only applied at the bottom periphery of the battery, and it is actually only applied to the midframe, then the battery inserted.
