EEStor Ultracapcitor Battery lines up big contracts

The company said EEStor is developing a ceramic battery chemistry that could provide 10 times the energy density of lead acid batteries at one tenth the weight and volume. Lockheed Martin, the world's No. 1 defense contractor, plans to integrate and market EEStor's units for military and homeland security applications.

A highway-speed electric vehicle (ZENN) with an ultracapacitor from stealthy EEStor is due to roll out in the fall of 2009. While it will sell for a premium over similar gas cars, it will be affordable for mainstream buyers, the company says. Most likely it will come out in Europe first and the U.S. later. Zenn is expected to get its first samples of EEStor's energy storage units this year. http://news.cnet.com/8301-11128_3-9908050-54.html
