    Errrr ... the "upcoming Prius" won't use Li-ion batteries, if you mean the all-new 2010 model to be previewed at the Detroit Auto Show in January.
    It'll stick with tried-and-true nickel-metal-hydride cells until Toyota is absolutely, totally sure its Li-ion cells will behave to its standards.
    Toyota may introduce another, different hybrid with Li-ion cells, but they won't (initially) be in the Prius.
