A Texas startup says 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.

Dick Weir, founder and chief executive of EEStor, a startup based in Cedar Park, TX, says that the company has manufactured materials that have met all certification milestones for crystallization, chemical purity, and particle-size consistency. The results suggest that the materials can be made at a high-enough grade to meet the company's performance goals. The company also said a key component of the material can withstand the extreme voltages needed for high energy storage.

"These advancements provide the pathway to meeting our present requirements," Weir says. "This data says we hit the home run."
