EEStor, Inc. issued a short press release announcing that a third-party has certified that EEStor’s patented and patent pending Composition Modified Barium-Titanate Powders have met and/or exceeded a relative permittivity of 22,500.
In the few public statements made by the company several years ago, it had said that it anticipated that the relative permittivity of its then current powder would either meet and/or exceed 18,500, the previous level achieved when EEStor produced prototype components using it engineering level processing equipment.

The third party certification tests were performed by Texas Research International’s Dr. Edward G. Golla, PhD., Laboratory Director.
EEStor said that it feels this is a “huge” milestone which opens the advancement of key products and services in the electrical energy storage markets of today. The automotive and renewable energy sectors are a few of the key markets that would benefit greatly with the technology.
EEStor, Inc. is working to develop solid-state electrical energy storage units (EESU’s) in the form of batteries and capacitors. The EEStor EESU—a high-power-density multi-layered barium titanate ceramic ultracapacitor—is expected to provide energy densities of more than 450 Wh/kg and more than 700 Wh/L; charge in minutes; and have extremely long life.
