Milestones Achieved by our Company: Over the last period, the company conducted an extensive research and development program which was centered on the synthesis and fabrication of dielectric materials with high dielectric constant (k), far exceeding those of the present-day materials. This work resulted in a new generation of dielectric/ferroelectric materials with dielectric constant of several millions. This new material has regular losses of 1-2 %. This is the largest dielectric constant reported in industry or literature.
Based on this development, it is now possible to design and fabricate a single layer capacitor with much higher energy storage capability (in accordance with equation E=1/2CV2), while maintaining the same area and thickness of the capacitor. Another important milestone achieved in this period is developing the technology to synthesize dielectric materials with high surface area in the form of a thin layer in a matter of minutes, opening the door for mass production of devices, both in a single layer (without electrolyte) and multilayer forms.
The advantages and benefits that the present program offers can best be appreciated by comparing the pros and cons of an 85-kWh unit that will be produced by Ultra-Cap’s and the same power Tesla battery.
The company’s battery will weigh just over 50 kg as compared to the massive 544 kg of Tesla’s 85 model. The energy density is approximately 3,500 (Wh/Liter) which is 5 x higher than Tesla's 85 KW Li-Ion battery .
The key advantage of our approach to solving the energy density problem of our ultra-capacitor, is the incorporation of dielectrics with a very high specific capacitance rather than relying on high charging voltage, such as is the case with our competitors, including EEStor which uses the charging voltage of 3,500 V.
By developing a very high capacitance dielectric, it will be possible to store larger amount of charge at lower voltages (all the way to 220V) thus making it easier to charge and possibly eliminating the need for specially constructed charging stations. In comparison with Tesla’s battery, which requires a charging time of 12 hours, Ultra-Cap’s units will be fully charged in only 4 minutes. These results can lead to a total reduction of cost of around 30% per kilometer.
