All of these batteries were non-rechargeable. It was stated that rechargeable ones, such as proposed for the Chevy Volt are less dangerous Of course one has to compare the hazard of a 400 lb lithium iron battery against that of 80 lbs or more of gasoline, the latter has been used for many years.

This is a hybrid! Would Sealed Lead Acid batteries that had to be replaced every 5 years at $1,000 and only go 30 miles on battery power really be inferior to a "lifetime" battery that would go 40 miles and cost $20,000? Build the damned car now instead of waiting for advances that may never come. The need for Li Ion batteries is total BS. This is a hybrid!

The newest 123 Battery is a Nano type battery that does not have the same fire hazard characteristics of an older laptop type battery. These batteries will NOT EXPLODE if dropped. This is the newest generation Lithium battery, safer, and will charge in minutes instead of hours without any Thermal Issues. I have been abusing a very close cousin of these batteries for over a year and have of yet gotten any of them to catch fire. If shorted these newest batteries have an internal disk that shorts and disables the batteries. It takes a lot of overvoltage and abuse to make these batteries pop the internal disk. They also do not suffer the extreme heat issues that the Laptop Lithium batteries experience. They have a cycle life that far Exceeds any nicad or nickle metal battery I have ever seen!

Carbon Nanotube Ultracapacitors (not strictly batteries). Double irony - carbon may be the answer to carbon emmissions and the GM Volt could end the dominance of Alessandro Volta's battery design. There is a small unquoted company called the Double Carbon Batterey Company that clalms to have product ready for market. (Just ripe for a big car company to snap it up!) Probably.

It seems GM is ready to go production with this vehicle and a mainstream price is needed. Id bet they are planning to go with the best existing technology. I agree that many future options will be able to sub-in as the fuel source and the battery. This Double Carbon battery sounds interesting, are you referring to the nanofiber battery under development? Councilor
