Technology
In a supercapacitor the energy stored depends on the effective area of the electrodes and the dielectric properties of the electrolyte.
Superdielectrics technology represents a significant breakthrough in electrolyte development that could increase energy densities of supercapacitors to that of existing battery technologies, but with all incumbent performance characteristics of supercapacitors.
Superdielectrics has developed exceptional technology involving patented electrically active polymers, as validated by Surrey and Bristol universities While the majority of recent progress in supercapacitor performance has been made through developments increasing the effective surface area of electrodes, Superdielectrics’ breakthrough is in electrolyte performance, this discovery has the potential to develop ultrahigh energy and power density supercapacitors.
“Summarised that the Company’s electrolytes enjoy performance characteristics “three to four orders of magnitude [1,000 to 10,000x] larger than the geometrical Capacitances of carbon electrodes in conventional solutions.”
“Progress in the development of Superdielectrics novel hydrophilic polymer electrolyte has continued in the past year with significant improvements in both the maximum operating voltage and the areal capacitance achieved in the laboratory.
These developments if combined into a single cell make it reasonable to project the achievement of energy densities in the range 40-60 Wh kg-1 in the near future with high probability
“The research data now available does not indicate any theoretical reason why higher energy densities should not be achievable given appropriate levels of research effort; indeed the capability of the technology appears to be open ended.”
“In this report the University concludes: “Our studies provide an independent and robust quantification of the outstanding electrochemical properties of the SD membrane and their potential for developing ultrahigh energy and power density supercapacitors.”
