A supercapacitor is an electrochemical device which stores and releases electricity like a battery, but instead of storing as chemical energy, it stores in the electric field.
One of the supercapacitor advantages is it can be charged in a few seconds instead of hours like a battery. Generally, supercapacitors are also known to have long operational lifetimes compared to batteries, with minimal change in performance.
However, current supercapacitors still require higher energy density, they can be expensive to fabricate, are rigid, have a poor working-temperature range and use a liquid electrolyte soaked separator.
There are many ways to store energy: fuel cells, batteries, solar cells, electrolytic capacitors, hybrid electrochemical capacitors (supercapacitors). Each of them has unique properties that are suitable for certain applications.
We are aiming for a device with highest specific power and energy.
The novelty of our device is that it combines the energy density of batteries and the power output of capacitors into one with extra advantages. The active material for the electrode is carbon based, of which our innovative process transforms them into highly capacitive electrodes. The Poly-Scap can be assembled in a variety of ways, with the initial prototype as displayed below. We have patented our technology and are working on the commercial design.
