A newly-granted US patent (PDF) for the upcoming ultracapacitor technology from secretive Texas-based EEStor contains a ton of detailed information about their near-mythical Electrical Energy Storage Unit (EESU), which has the potential to revolutionize transportation and our energy infrastructure.

Apparently one EESU weighs 281 pounds, has a volume of 2.63 cubic feet, can be fully charged in 3-6 minutes, is completely unaffected by temperature, will not explode or catch fire in an accident, and provides 52 kWh of electricity (nearly the same amount of energy the Tesla Roadster battery can hold, which reportedly takes the Roadster about 240 miles).

Whatever you do, don’t call it a battery.

A research group at the University of Texas at Austin has taken a carbon-based nanomaterial called graphene, and developed it into a device that has the potential to vastly improve upon the energy storage capacity of batteries. Reportedly, graphene could also double the current maximum storage capacity of the group of battery alternatives known as ultracapacitors.

If the research group’s findings bear out when applied to reality, it could mean a complete phase change in the way we approach energizing not only our transportation sector, but our entire energy infrastructure.
