Electrochemical power sources are of interest since they can be designed to be more sustainable and more respectful of the environment. Among these, electrochemical supercapacitors are currently being investigated in various academic and industrial laboratories because they can be used as complementary charge storage systems to conventional batteries in applications that require peak power pulses. Research and development in the field of supercapacitors has focussed onto the development of electrode materials that are characterized by high specific capacitance, rapid response, environmentally friendly, and made of low-cost abundant elements. At the same time, cost-effective synthetic methods which are easily scalable up are necessary for the full implementation of this technology.The current proposal is concerned with a market study related to graphene nanocomposite materials for electrochemical devices such as supercapacitors and a method of producing thereof. The electrodes derived from such composite can operate in a large voltage window of 2V which goes beyond the usual potential window of 1V found with aqueous electrolytes. Hence, this invention offers a practical solution to the main factor limiting electrochemical capacitors in terms of energy density operating in aqueous electrolytes. In addition, the synthetic procedure which is based on the electrochemical exfoliation of graphite foil in an acidic medium containing an oxide precursor, is an economic and simple one-step method to produce the graphene composites on the gram-based scale in few hours. This market study will provide a real feedback from the industry essential to confirm the commercial potential of the technology.
