EV Ultracapacitor Energy Storage Device
Dielectric constant of several millions is a scientific breakthrough
Our conclusive three year research program focuses on the development of a new generation of high capacitance ceramics with electric charge storage capabilities far exceeding those of existing ceramics.
Due to ever increasing demand for energy storage and its transport, there is a need for a new generation of materials and devices capable of storing large amounts of electric energy without problems associated with disposal and environmental pollution.
Historically, the acid based batteries have been the most common way to store electrical energy. However, this
technology has always been limited by its slow charging time and degradation of performance after a relatively small number of charge cycles.

High energy density capacitors (recently called “ultra capacitors”) overcome the drawbacks of standard acid-based batteries by exhibiting charge times measured in seconds, and a small decrease in performance over millions of cycles.
The most promising application of these next generation energy storage capacitors is integration into vehicles, where they will store energy for emission-free cars that do not run on fossil fuels. This technology will also overcome the out-of-service hours that current electric cars require to recharge, one of the largest consumer barriers for widespread market penetration.
With the new generation of solid-state batteries, the release of electricity will not be limited by chemical reaction rates, allowing electric cars using this technology to fully recharge in seconds as opposed to hours.
UltraCap is currently looking for funding to develop the project further.
‘We can make the ceramic di-electric much thinner and lighter without losing electrical capacity and create pocket size car batteries in the near future.’ The technology has the potential to revolutionize the way electrical energy is stored and transported. Due to high energy density and small size, it will be possible to charge the device far away from urban areas where electricity is abundant and inexpensive and then transport it to urban areas where it is needed the most.´
