“…The high S BET and V tot indicate high porosity in the porous carbon, which provides more active sites for electrolyte ions to adsorb on the carbon electrode surface. According to Wu et al [65] and Chen et al [66], the size of salt and ionic liquids that commonly used in polymer electrolyte studies are $0.1 to 0.6 nm and 1.2 to 1.5 nm. Based on the BET analysis, the pore size of porous carbon in this work is 1.89 nm.…”

“…Also, combinations of nanostructural variations from both MO and carbon materials in nanocomposites is a worthwhile avenue. Hence, tailoring nanomaterial properties towards high energy storage capabilities without sacrificing power density is crucial .…”

“…Imperfections, carbon orientation and phases in nanostructured carbons can act as sites of electron transfer. A large crystalline structured material with large d‐spacing would be expected to have high charge accumulation abilities . In EDLCs, high active electrode surface areas, typically greater than 1500 m 2 g −1 , and tiny distances between charges theoretically implies high capacitance values .…”

“…A mismatch will render some pores of carbon nanomaterials inaccessible to the electrolyte and this means poor utilisation of the electrolyte ions in forming the double layer . Also, with the need to optimise pore sizes for the operational mode and electrolyte in terms of ion size and mobility , the implication is that the subject of pore sizes in ECs is a critical area that still requires focussed studies.…”

“…Hence, nanotechnology enables fabrication of novel carbon nanomaterials, nano‐structures and nano‐devices with tailored properties for EDLCs . In fact, from the electrode point of view, energy storage and power delivery rate of nano‐structural carbons can be enhanced by tuning their porosity to match the electrolyte ion size . For example, in a recent study, pores were tailored from microporosity (0.6 nm) to mesoporosity (40 nm) by varying the thickness of silica on yolk shell carbon nano‐spheres .…”

SUMMARYSustainable and renewable energy resources, as well as energy storage systems (ESSs), are amongst the current and critical global requirements. A comparative discussion on batteries, fuel cells and electrochemical capacitors (ECs) is presented. The mechanisms involved in various classes of ECs are also elaborated. Additionally, a historical background highlighting some of the major steps associated with EC development over the years is discussed in this review. In particular, carbon nanostructured materials have high potential in the development of ESSs, and hence this review presents an insight on the current ESSs with a strong bias towards these materials as ECs. The current status of carbon nanomaterials, such as carbon nanotubes, nanofibers, nano-onions, nanorods, fullerenes and graphene nanosheets, in ECs is reviewed. The associated effects of nanostructural parameters, such as pore sizes and specific electro-active areas, amongst others, in terms of energy storage capabilities are also discussed. Typical physicochemical characterisation techniques, which enrich understanding of their characteristics, are also reviewed. The discussion views set platforms for a variety of unique carbon nanomaterial designs with high prospective specific capacitance. Key porosity tailoring protocols, such as chemical activation, introduction of heteroatoms in carbon nanostructures and template synthesis methods, are also reviewed. The effects of other device components, such as electrolyte ion size and solvent system, electrode design and use of binders, to the overall capability of EC, are also discussed.
