I read some blurbs and articles about work with zinc-air.  Apparently, 
some of the problems with zinc-air have been solved.  Zinc-air is known 
to have an energy density about twice that of lithium, but is still much 
safer.  Zinc is also more abundant and cheaper than lithium.  A very 
good and almost-completely-untapped-thus-far source for lithium is in 
South America, and the zinc-air design is still to be proven, so I 
wouldn't count lithium out yet, however.
