NiMH worked well enough for pure electric RAV4 EVs, or Solectria's Sunrise, which added composite construction like Tesla's Roadster. Another un-mentioned battery technology with a decade of proven capacity is the thermal Zebra NiNaCl from MES-DEA. Lithium chemistry is far from universal. The question comes down to a given level of performance for the lowest price.
