Date posted: 05/08/2008 Texas startup EEStor has stated that it has taken a big step toward high-volume production of an ultracapacitor-based energy-storage system that, if claims hold true, would far outperform the best lithium-ion batteries on the market. A battery with a lifetime three times longer than that currently available would be a godsend for mobile computing devices, and that is what the company is claiming. Many have questioned EEStor's claims, pointing out that the high voltages needed to approach the targeted energy storage would cause the material to break down and the storage device to short out. There would be little tolerance for impurities or imprecision--something difficult to achieve in a high-volume manufacturing setting, skeptics say. But Dick Weir, founder and chief executive, is dismissive of such reactions. "EEStor is not hyping," he says. Representatives of the company said in a press release that certification data proves that voltage breakdown of the aluminum oxide occurs at 1,100 volts per micron--nearly three times higher than EEStor's target of 350 volts. "This provides the potential for excellent protection from voltage breakdown," the company said.
