The automotive lithium-ion battery industry is in it's infancy. Aside for some relatively small companies making limited production prototypes, there will likely be no substantial lithium-ion powered EVs on the road until the Volt arrives in 2010.

Forbes has published a decent review of the current state of the technology. They compare GM and Toyota as the tortoise and the hare, with Toyota cautiously moving ahead, at best putting li-ion into a limited fleet of PHEVs in 2010, and with GM racing to mass produce the powerful battery-driven Volt.

Prabhakar Patil who is the CEO of Compact Power Inc., one of the two companies building prototype Volt battery packs, is quoted as saying, "What I worry about is a black eye--if somebody puts a battery on the road prematurely, it would hurt the entire industry."

The other battery pack team includes li-ion supplier A123 Systems, whose founder Ric Fulop said "Somebody lit a fire under [GM's] butt in 2006," and "I've never seen a large company move so fast and put so many resources behind something."
