“…Recent studies from the world's leading laboratories in the field of high-capacitance chemical current sources have demonstrated the feasibility of using carbon nanomaterials as electrode materials [3,[11][12][13][14][15][16][17][18][19][20][21][22][23][24][25]. New approaches for obtaining graphene make it possible to develop supercapacitors able to accumulate and release energy for short periods of time, thereby allowing them to be employed in various technical applications (e.g., electric transport, autonomous current sources, electronics, etc.…”

“…The latest research results show that the use of graphene as an electrode material for supercapacitors increases the specific energy storage density of those devices due to an increase in the specific surface area up to 1500 m 2 /g and very high conductivity [11]. The new production technology developed for supercapacitors is based on highly porous multi-layered or few-layered graphene nanoplatelets (GNPs) (Fig.…”

“…Its deposition over GNPs increases the electric conductivity and alters the porous structure of the material. The surface area, porous and crystalline structure and electrical properties of the final nanocomposite can be varied over a wide range depending on the carbon precursor nature, GNP parameters, and synthesis and activation conditions [8,10,11].…”

In current practice of developing supercapacitors, graphene appears to be a promising electrode material due to its unique physico-mechanical properties. Using graphene-based electrodes in supercapacitors opens up new prospects, primarily, the range expansion of operating and design parameters to enable the realization of higher operating voltage levels and to ensure thermal stability and an increase in the number of charge/discharge cycles.In the present research, electrotechnical parameters and characteristics of a supercapacitor with electrodes made of a composite material consisting of graphene and nanoporous carbon were studied during charge/discharge processes using the voltmeter-ammeter method. The results obtained demonstrate that applying graphene as an electrode material for supercapacitors allows for charge/discharge mode implementation, provided that the time to charge the supercapacitor up to the capacitance value of 5.10 F is 5 s and the supercapacitor operating weight is 5.04 g.

“…A second class of hybrid SC is represented by devices, combining the electrode of an EDLC with a composite electrode, using carbon-based material (for example, carbon nanotubes) that incorporates either a conducting polymers or a metal oxide [6,18,19]. Such devices are also called asymmetric hybrid SC.…”

Supercapacitors Technical Requirements for New Applications

The supercapacitors (SCs), also called ultracapacitors or electrochemical capacitors, are devices with a very high specific power and high capacitance, available for a long period of time with negligible deterioration, that have been historically proposed in small applications (memory back‐up in consumer electronics and storage systems for microsolar power generators) and now are proposed for high power/energy applications, such as hybrid and electric vehicles, power quality systems and smart grids. The advancements in new materials and the rapid growth of more demanding storage systems in a variety of applications have created a lack of universally accepted definitions of these devices and, consequently, a real difficulty in describing developments and progress in the SC field. This paper contains a brief survey of the history of the SC development, which is strongly related to the evolution of the SC technologies, tentatively classified in symmetric, asymmetric and hybrid. A short presentation of key parameters has been given to introduce the description of new applications with large SC devices, covering transport, industrial and electric utility sectors, with some reflections about the foreseen impacts on the future market more than quadrupled in 5 years up to almost $877 million worldwide.
