EEStor Provides Additional Test Data Following June 5, 2013 Testing And Update On Current Status

CEDAR PARK, Texas, June 26, 2013 /PRNewswire/ -- On June 5, 2013 EEStor, Inc. had Criteria Labs certify certain aspects of a current layer of its electrical energy storage unit (EESU) that had been produced on April 29, 2013 using new materials that provided both high capacitance and high resistance simultaneously. The capacitance and resistance of this new layer material are expected to be increased using EEStor, Inc. proven proprietary processing equipment and processes.

The following data from new layer material was certified by Criteria Labs on June 5, 2013:

Average capacitance of the four layers = 0.22 micro farads

Average Resistance of the four layers = 10.7 mega ohms    

Subsequently, on June 26, 2013 EEStor, Inc. had the area and thickness of the new material layer certified by TesCom at EEStor, Inc. using TesCom calibrated EEStor, Inc. equipment.  TesCom was called in to certify these results due to scheduling issues with Criteria Labs. Subsequent testing will be conducted by Criteria Labs. The equipment used to measure the area and thickness was certified by TesCom, a calibration company which was selected by Criteria for the certification of the equipment used in their June 5, 2013 certification process.

The following data from new layer material was certified by TesCom:

Average thickness of the four layers = 25.1 microns

The area of each of the four layers = 0.403 centimeters squared

The average volume of the four layers = 0.00101 centimeters cubed

Using the certified capacitance, area, thickness, and volume the following relative permittivity was calculated:

The average relative permittivity of the four layers = 15,476

EEStor believes that relative permittivity of 15,476 and an insulation resistance of 10.7 mega ohms of this initial new material test layer represents a major breakthrough in EEStor, Inc. new dielectric materials.  By comparison, a 0.22 micro farad 100 V capacitor manufactured by EPCOS has a volume of 0.216 cubic centimeters or 214 times bigger than EEStor's equivalent capacitance.  Capacitance is directly proportional to energy storage and this high capacitance volume also indicates the ability of EEStor, Inc. to potentially exceed its energy storage operating targets.

CURRENT DEVELOPMENT

EEStor has now successfully enhanced the new dielectric layer of its EESU and initial internal results indicate the following:

• Capacitance vs. voltage has been increased
• Layer resistance has been increased
• Capacitance has been increased
• Constituent tuning has been improved which allows the potential for continued success in product development

NEXT STEPS

As soon as EEStor reaches its optimal constituent tuning of its latest layers it will complete the testing and certification with Criteria Labs. The tests and certification of these samples will include:

• energy density
• dissipation factor
• resistance
• capacitor area
• total layer thickness
• leakage current at multiple voltages including voltages over 1000V
• dielectric layer thickness
