These companies play the prices very close to the vest, Cabe. But if we do a little arithmetic, we can get in the ballpark. A 500-kWh battery at $1,000/kWh would be a half million dollars. If the battery costs are coming in lower, say $500/kWh, it would be $250,000.

Looking at these batteries and their elaborate housings it hits me; how amazing that we can pull enough resources out of the earth to make it all. The resources seem endless, though I know they are not.

That Grid lithium battery must cost a fortune. Do you know the price?

AnandY, actually the range depends on the weight of the car and the power of the motor. 

One of the other issues with batteries is the amount of time to charge them.  A large pack like the one you mention, may take hours to charge (unless you have a special charging station).  This is just another "problem" to be solved.

Image problems?

Nice slide show, Chuck. lithium-ion batteries have come a long way, but for autos, they probably have an image problem -- cost and safety -- they have yet to overcome.

Envia Systems is doing a great job in liitium-ion battery development. The electric car industry faces two major challenges: the high cost of batteries and their limited range between charges. Envia Systems, a startup developed a rechargeable lithium-ion battery with an energy density of 400 watt-hours per kilogram, the highest "energy density" known. They claim that once the electric car is fully charged then car can run upto 300 miles.
