The Universe Exists for My Amusement

Via Slashdot, we learn EEStor is Granted a New Patent on the EESU Revealing Extensive Details.

In any event,on December 16th EEStor was granted a US patent for their EESU. The patent is a highly information-rich document that give a remarkable insight into these potential devices. EEStor notes “the present invention provides a unique lightweight electric-energy storage unit that has the capability to store ultrahigh amounts of energy”.

The core ingredient is an aluminum coated barium titanate powder immersed in a polyethylene terephthalate plastic matrix. The EESU is composed of 31,353 of these components arranged in parallel. It is said to have a total capacitance of 30.693 F and can hold 52.220 kWh of energy. The device is said to have a weight of 281.56 pound including the box and all hardware. Unlike lithium-ion cells, the technology is said not to degrade with cycling and thus has a functionally unlimited lifetime.

If the EEStor supercapacitor:

• works
• can be produced cheaply
• reliable

then this represents a huge leap forward in energy storage. Those are a lot of ifs, though… standby…
