Potential Game Changing Ultracapacitor Technologies

EEStor Head Office , Cedar Park, Texas
A little known company from Cedar Park, Texas called EEStor may be gearing up for scalable manufacture of 52kw EESU's (Electrical Energy Storage Units). These units weigh only 152kg but can power an average car for 350 kilometres. Here are some good blogs

The interesting things to note about the EEStor technology:
  • The cost of 52kW EESU is expected to be between $2,000-$3500. Substantially cheaper and safer than Lithium Ion batteries.
  • EESU recharges in as little 7 min. (requires high voltage, it will take 4 hours on 220v). If you had a recharging unit at home you could use off peak power to charge it and then recharge your car quickly with the unit.
  • Power density will be 10x average lead acid batteries and 1.5x the best available lithium ion batteries.
  • Unlike lithium batteries, materials used in the EESU are non-toxic, non-hazardous and non-explosive. They include barium (Ba), calcium (Ca), titanium (Ti), zirconium (Zr), manganese (Mn), yttrium (Y), neodymium (Nd), forming the composition-modified barium titanate powder, and the metals: nickel (Ni), and copper (Cu) .
  • The patented approach uses ceramic and integrated-circuit technologies to that will enable EEStor to mass produce EESU's in an automated factory.
  • The following big names are involved with EEStor or its partners.
    • Al Gore ex Vice President (now on Kleiner Perkins Board)
    • Michael Dell (Founder Dell Computers) - [possible angel investor]
    • Mort Topfer (ex Dell)
    • Colin L. Powell, (the former secretary of state)
