Dais receives patent and demonstrates energy storage capabilities

TAMPA, Florida -- Dais Analytic Corporation have announced the United States Patent Office awarded U.S. Patent Number 7,990,679 to Dais. The patent, entitled "Nanoparticle Ultracapacitor" uses Dais's commercial family of Aqualyte™ nano-structured materials to create an energy storage mechanism projected to have performance and cost advantages over existing storage technologies. The patent was filed on July 16, 2007.

Dais, working with experienced personnel at the University of Florida under a cooperative testing agreement, has used this patent's concepts to create a functional energy storage prototype device named "NanoCap".

NanoCap is a form of ultracapacitor which when fully developed we believe will be useful to power a broad range of applications including most forms of transportation, energy storage (especially useful as a storage media for renewable energy technologies), telecommunication infrastructure, transistor gate dielectrics, and consumer battery applications (cell phones, computers, etc.).

The Patent's examples show an energy storage device capable of:

• Extraordinary dielectric constants as NanoCap employs a unique ability of adjusting to the presence of an electric field;

• Potentially greater energy storage densities than today's known best lithium ion batteries;

• Increased capacitance;

• Increased ability to cycle;

• Higher power and energy density;

• Reduced weight; and

• Equal or lower cost.

"NanoCap – which is made possible by manipulating the attributes of our nano-materials – is truly exciting for Dais. We believe it again demonstrates the power of the Aqualyte™ family of plastics which we continue to project to be able to provide long term solutions to our growing infrastructure needs for cleaner air, energy efficiency, and clean water." said Scott G. Ehrenberg, Chief Technology Officer of Dais. Liwei Cao, PhD, Senior Polymer Chemist at Dais, and Mr. Ehrenberg are the cited inventors of this US Patent (7,990,679).

Dais plans to release further technical details related to the advancement of Aqualyte™ in the energy storage application soon. The full text of the patent can be found at the United States Patent and Trademark Office website, http://patft.uspto.gov.
