EEStor has finally broken its
silence and I am not surprised. The last
material announcements reflected confirmation that the production of the
working nano powder met the specifications necessary to achieve the program’s
ultimate goal. This attracted the
attention and partnership of Lockheed Martin as well it should have.
Their pronouncements avoided the
obvious next challenge of actual component fabrication which I expected to be
challenging at the least. I assumed that
they understood the necessary configuration that they needed to achieve since
it would be easy to model going in.
They have achieved void free
layers and have made excellent progress in general.
Otherwise, they are not yet
getting the necessary permittivity and this is pretty fundamental. Thus predictions of deliverability will be
premature at best. You can put the
Champagne back in the cooler.
EEStor Provides a Progress Update on the Development of its Electrical
Energy Storage Units

CEDAR PARK, Texas, May 15, 2012
/PRNewswire via COMTEX/ -- EEStor Inc. ("EEStor") announced today
that it is providing an update on the progress of its ultra-capacitor based
energy storage technology.
EEStor has been working on the
development of single layer Electrical Energy Storage Units (EESUs) as a step
toward full commercial units. The single layers are generally around 20 microns
in thickness with an area of 0.25 inches square. EEStor has successfully
demonstrated a process that yields layers that can handle an operating voltage
in excess of 3500 volts, have a dc resistance of greater than 700 terra ohms,
and a dissipation factor of 0.005. The process of manufacturing the layers has
evolved as EEStor has worked on improving the reliability of the layers. EEStor
has recently focused its efforts on elimination of voids within the layers to
improve the energy storage capabilities of the EESUs. EEStor has recently
made major progress in that it is now successfully producing layers which tests
indicate are void free.
The layers now being produced
have very small internal self-discharge and crossover losses. These
layers have been cycle tested by EEStor and have achieved over 1 million full
cycles at a rate of less than 30 seconds per cycle. Each cycle consisted of charging
to 3500 volts followed by discharging to zero volts. The EESU layers have
better self-discharge characteristics and lower losses in the charge/discharge
cycles than other known competitive energy storage technologies. Improvements
have been made in the film morphology and fabrication requirements to
facilitate the use of automated manufacturing. However, the most recently
produced versions of the EESU layers have been tested by EEStor and in EEStor's
opinion do not yet achieve the level of permittivity necessary for commercial
production. EEStor is now working on improvements in the film morphology
which it believes will allow it to significantly increase the permittivity and
energy storage capabilities of the layers.
The performance of the EESU layers
has not been independently tested. Once EEStor has improved the permittivity of
the EESU layers, it will commence third party testing and certification. The
third party results will lead to a detailed analysis of the technology's
performance. Following independent certification of layers, EEStor intends to
build multiple layer EESUs to demonstrate the effectiveness of the technology.
EEStor has been developing production systems that have a level of automation
and throughput capability that EEStor believes can be improved and scaled
quickly.
About EEStor Inc.Headquartered
in Cedar Park, Texas, EEStor Inc. is dedicated to the design, development, and
manufacture of high-density energy storage devices. Utilizing revolutionary
ultra-capacitor architecture and environmentally friendly materials, the EEStor
technology will compete against existing battery technologies.
