Prudent said:Lithium-Ion batteries are the most efficient way to store electricity today, but I suspect we will find that there are even better technologies down the road.
In fact, my original reason for moving to Silicon Valley about a dozen years ago, before I got distracted by the Internet, was to do a Ph.D. at Stanford in the physics and materials science of high-energy density capacitors, specifically for electric vehicle applications.
Prior to that, I had worked for two summers at a small company called Pinnacle Research, which focused on ultra-capacitors.
Capacitors have the advantages of a quasi-infinite cycle and calendar life, extremely low charge/discharge losses, and charge times measured in minutes (if you have high voltage and thick wire) for a car-size pack.
If the capacitor energy density problem is solved, the gasoline vs. electric car contest goes from being a contestable fight to gasoline getting the Wrestling Smackdown.
Ethanol, Ethanol Everywhere, Time to Stop and Think

The energy storage densities of these energy carriers are far higher than even a lithium polymer cell. See, for example, https://wiki.xtronics.com/index.php/Energy_density. One drawback for hydrogen, however, the Achilles heel, is a distribution infrastructure. However, if ammonia can be used with a suitable reformer, then a fuel cell vehicle would be superior to a battery-powered electric vehicle.
I don't believe that the drive train would be different for a fuel cell vehicle versus a battery powered one. However, there are definitely differences in balance-of-plant componentry.
