I thought you basic doubt was the ability to have an automobile powered by a battery. That has been done quite a while ago. The Tesla's range is 245 miles. This battery is just an improvement.

No the basic issue is that exxon is claiming that they can downsize a car battery to the size of a PC’s battery. That simpley can’t happen without a loss of range (miles per recharge). The film allows for more anodes and cathose which will give batteries more short-term power (better acceleration) but the need is still there for all of the chemicals that have the ions.
