There are several non-rechargeable lithium batteries on
the market, and
they most certainly _should not_ be recharged. Typically they are used for
cameras and other items that need short duration high current pulses of
power.
I heard the advantage to Lithium batteries over Alkaline is that Lithium
provides steady voltage right up until it is dead, where an Alkaline
looses voltage as it dies.
Any truth to that? Or is it simply Lithium provides more amperage at a
given voltage?

Both are true. They hold the voltage level more steady as they are used,
and they recover from pulsed current drain faster then an alkaline does.
This is why they are ideal for cameras with flashes and similar electronic
equipment. There would be no real gains to using a Lithium cell in say a
walkman, since it has a slow but steady current drain over a long period
of time. Alkaline cells are less expensive to manufacture, so they cost
considerably less than a Lithium cell.

Lithium cells are also better at really low temperatures. And they
have a very nice shelf-life. Which makes them possibly approriate for
an outdoor electronic thermometer that takes very little power if you
live in, say, Minnesota in the winter.
