OK, now two folks have opined that lithium batteries will probably
work in a smoke detector, even though one pointed out that the
Li battery has ~16 ohms internal resistance versus ~.8 ohms for
the alkaline. It would seem safer to contact the detector manufacturer
to ask whether it's OK rather than assuming it is, given that they
all do specify using certain batteries.
