Results continue to show promise. This confirms that they are now
able to produce operational layers and to drive a creditable
response.
This project has been plagued by research optimism driven by investor
enthusiasm. I personally find the development time completely
reasonable. I would have been suspicions if they had been clipping
along at the speed demanded by observers.
EEStor remains the best possible protocol available for energy
storage. They have proven after years of effort that they can
produce the necessary powder. It is now all about engineering a
working product that can then be perfected over even more research
and time.
The design concepts are as difficult as playing with a box of
marbles. The devil is in the dimensionality. It would be really
neat to design some DNA to do the hard work for us. That is even a
plausible proposition today.
EEStor, Inc. shows
preliminary results from Paraelectric Dielectric path
CEDAR PARK, Texas,
Jan. 28, 2013 /PRNewswire/ -- EEStor, Inc. ("EEStor") is
pleased to report the materials science context for their work and
preliminary (pre-certification) results from energy storage layers
built in its pilot production facility during early final tuning. The
preliminary results show EEStor's patented and unique composition
modified barium titanate (CMBT) powder delivers the benefits of
solid-state energy storage when used as a fundamental constituent in
a paraelectric dielectric.
On Dec. 28, 2012,
EEStor's President Richard Weir hosted Dr. Rick Ulrich, Professor of
Chemical Engineering at the University of Arkansas, for a review of
and conversation regarding EEStor's work in pursuing a paraelectric
dielectric path for high density energy storage applications. In
particular Dr. Ulrich was provided access to data and materials
related to EEStor's CMBT powder.
Dr. Ulrich made the
following comments regarding his meeting and on the test data shown
below:
"Dielectrics with
the properties shown here would provide unprecedented amounts of
capacitance per area. The possibility of obtaining
ferroelectric-sized permittivities with the stability of a
paraelectric material is very exciting. A dielectric with a
permittivity of 1000 is considered high in current capacitor
technology, so materials with the permittivities reported here would
be an important breakthrough."
"Capacitor
dielectrics that show very large permittivities tend to lose storage
capacity as voltage increases. It's long been a goal of the
dielectric community to solve this problem."
"Materials like
this would find immediate applications in both signal and power
electronics."
"While there is
still work to do in order make these dielectrics suitable for
powering electric cars, this level of power storage represents a
significant advance in the art."
Preliminary EEStor
results and next steps
In prior press
releases, EEStor has indicated certain tuning results where EEStor
had combined some, but not all, of the constituents of its dielectric
to show performance control of some of the parameters that would be
required in completed commercial energy storage layers. Engineering
tuning work provides the blending, mixing and curing data necessary
to optimize finished layer construction where all constituents are
combined. EEStor entered the final phase of tuning optimization of
commercial layers that include all necessary and desired constituents
in the fourth quarter of 2012. Preliminary results of one such
production run were recently retested and verified by personnel from
System Engineering and Laboratories ("SEAL"), a
professional engineering organization headquartered in Tyler, Texas
with the following results:
Manufacture Date of
tested layers was Nov. 27, 2012. SEAL have verified the following
parameters:

Capacitance measured

Dissipation Factor

Leakage current (mA) @
Applied V
Layer dielectric

Area of layer - 10^-6

Testing equipment used
included: QuadTech 1715 LCR Digibridge LCR, Keyence GT2-212K,
Yokogawa WT3000, Stanford Research PS350/5000B-24W
These data are not the
best results achieved by EEStor in any category but are shown to
indicate that the benefits of the paraelectric dielectric path are
being delivered through EEStor engineering processes and in a pilot
production line facility. The samples were chosen to show results
with low leakage, some for permittivity. Most importantly, as
applied voltage was increased across the samples, there was no
detectable degradation of layer capacitance or relative permittivity
(i.e.; polarization saturation), thus exhibiting fundamental evidence
of paraelectric behavior of the manufactured layers. Breakdown
voltages of the samples are not shown.
Next steps for EEStor
after final tuning the performance of the dielectric material will be
certification of pre-production sample layers produced by the pilot
production line. Layers will then be available for purchase by
qualified commercial buyers for their independent testing purposes.
After layer certification, EEStor, Inc. will work in conjunction with
commercial partners to customize and improve throughput of the
continuous pilot production facility specific to the needs of
customers.
