The secretive company EEStor has been quietly talked up by potential manufacturers eager to use their new EESU (Electrical Energy Storage Unit). At the same time, EEStor themselves has kept pretty quiet, which only builds the anticipation. This company’s technology is a unique, light-weight electrical storage unit (battery) that can store extremely high amounts of energy.

Sounds great, but so far, there’s no puddin, just heresay. Now the patent is out, having been granted and therefore publicly published. If the design is correct (and works), then this is truly a revolutionary step forward in electrical storage technology.

The EESU incorporates an aluminum coated barium titanate powder that is immersed in a polyethylene terephthalate plastic matrix. I don’t know what any of that is either, but it sounds pretty impressive. Looking at the pictures (Woo hoo! It’s got pictures!), though, I think that means there’s a plastic box with some powder floating around in a liquid and all that somehow stores electricity. I’m not a chemist, so that’s about as good as it gets for my understanding.

Anyway, the rest of the numbers are impressive, for sure. This little (relatively) battery can hold 52.220kW/h of energy and weighs in at only 281.56 pounds (including all hardware). This technology is also not supposed to degrade with use and cycling, unlike lithium-ion. This means it can be used (theoretically) forever.

Here’s a comparison to make those numbers more impressive: the Tesla uses a 53kW/h battery pack that weighs in at a whopping 950+ pounds total weight. Plus the batteries, being li-ion, are rarely decharged below 20%, so their capacity is actually smaller in actual use. This means that the EESU weighs about 1/3 as much, holds just about as much energy, and actually holds more because it can be thoroughly drained without adversely affecting the battery.

Impressed yet?

Now the question is whether this ultra-capacity battery will actually work and whether it really exists in physical form. Right now, it’s just on paper for all anyone knows. True to their usual behavior, EEStor is being quiet about whether they have a test-able prototype.
