Verification of Intellectual Property

Superdielectrics initial strategy has been to independently test and validate the discoveries made during the Superdielectrics research programme at the University of Surrey. Such validation was undertaken by Professor David Fermin of the University of Bristol:

August 2017 Bristol Report

“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.”

July 2021 Surrey Report

“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.”

October 2021 Bristol Report

“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.”

Intellectual Property

Superdielectrics aims to use the IP portfolio to create barriers to entry for large addressable markets which are high growth and high margin. Superdielectrics is seeking world leadership in a crucial energy storage technology. Patents have been granted in several territories to date, including Europe and the US.

Cell Energy Density

Superdielectrics aims to increase the energy density of the first prototype cells through technology development. The research programme will be focused on increasing the energy density of prototype cells by reducing weight and increasing capacitance.

To deliver on this objective the Company will aim to recruit additional highly experienced scientists, engineers and support staff in the next 12-18 months. It will also be undertaking an extensive capital expenditure programme to continue to fit out its new facilities at the Emmanuel Building near Cambridge.

The Company’s other major objective is the development of higher energy storage prototypes. This requires the production of high-quality reproducible cells which exhibit consistent performance.

These cells are then electrically connected and packaged into a group of cells (i.e. a cell stack). It is the Company’s intention to continue to increase the energy density of prototypes to support the commercialisation of the company’s products.

Licensing the technology

The Company is planning to license the use of its IP for discrete applications. Since publicly announcing its ground-breaking discovery in December 2016, the Company has received a significant number of commercial approaches.
