“…CNTs are one-dimensional quantum materials with a hollow tubular structure and excellent electrical conductivity, large specific surface area, and high chemical stability (Lu et al, 2019). From the perspective of the wall structure, it can be divided into single-walled CNTs (SWCNTs) and multi-walled CNTs (MWCNTs), both of which have been widely used in the energy storage.…”

As an emerging energy storage device, the supercapacitor with high energy density, fast charging/discharging, and good cycle stability has aroused great interest. The performance of supercapacitors mainly depend on the electrode material. Manganese dioxide (MnO 2) has emerged as one of the most promising electrode materials for high theoretical specific capacitance, wide potential range, high electrochemical activity, and environmental friendliness. However, its deteriorated volume expansion and inherently low conductivity limit its development and application in supercapacitors. To circumvent the mentioned issues, the porous, thin film, or layered composite materials were prepared to enhance the electrical conductivity and specific surface area of MnO 2. Carbon materials are the ideal choice to compound with MnO 2 owing to their low electrical resistance, significant thermal stability, large specific surface area, and porosity. Up to now, several kinds of MnO 2 /carbon composites as supercapacitor electrodes have been designed and fabricated. Herein, we give a concise review of the latest researches on MnO 2 /carbon supercapacitor electrodes, focusing on the fabrication strategies and analyzing the influencing factors of electrochemical performance of MnO 2 /carbon materials. An outlook on the possible development directions in future of designing high-performance MnO 2 /carbon materials for the current challenges is also provided.

“…The porous nature of the fibers and films produced enables their hybridization with other species or compounds via the deposition of micro and nanoparticles on the CNTs/CNT bundles, via the infilling of the pores with liquids and/or polymers [22,[52][53][54][55][56][57][58][59][60]. As in the case of acids and halogens mentioned above this deposition may improve the performance of the fibers/films, however it is more often used to add new functionality.…”

“…As in the case of acids and halogens mentioned above this deposition may improve the performance of the fibers/films, however it is more often used to add new functionality. For example, materials hybridized with electrolytes are used in the construction of both batteries and supercapacitors [30,53,54]. Another example is composites, where a predefined network of CNTs ensures a very good loading fraction of the CNTs and thus better electrical and mechanical properties of the composite than for composites prepared with the use of CNT powders [22,[57][58][59][60].…”

Current studies of carbon nanotubes have enabled both new electronic applications and improvements to the performance of existing ones. Manufacturing of macroscopic electronic components with this material generally involves the use of printed electronic methods, which must use carbon nanotube (CNT) powders. However, in recent years, it has been shown that the use of ready-made self-standing macroscopic CNT assemblies could have considerable potential in the future development of electronic components. Two examples of these are spun carbon nanotube fibers and CNT films. The following paper considers whether these spun materials may replace printed electronic CNT elements in all applications. To enable the investigation of this question some practical experiments were undertaken. They included the formation of smart textile elements, flexible and transparent components, and structural electronic devices. By taking this approach it has been possible to show that CNT fibres and films are highly versatile materials that may improve the electrical and mechanical performance of many currently produced printed electronic elements. Additionally, the use of these spun materials may enable many new applications and functionalities particularly in the area of e-textiles. However, as with every new technology, it has its limitations, and these are also considered.

“…However, highly conductive carbon conductors are available in form of assemblies, which contain nanocarbons with a small length/size compared to metal conductors (Fang et al, 2020). The lack of progress in the fabrication of "single domain" continuous carbon nanotube and graphene fibers has offered the motivation for building carbon-based macroscopic assemblies with improved electrical, mechanical, thermal and electrochemical properties (Zhang et al, 2007;Lu et al, 2012Lu et al, , 2017Lu et al, , 2019Miao, 2013;Mäder et al, 2015;Kou et al, 2017;Dhanabalan et al, 2019;Foroughi and Spinks, 2019;Yang et al, 2020;Yin et al, 2020). In analogy with conventional metal wires, carbon nanotubes and graphene-based conductors have reached electrical properties of their metal counterparts, they possess numerous advantages, such as lower weight, high mechanical properties, sensing properties, resistance to extreme conditions, thermal and electrical conductivities (Cesano et al, 2013;Cravanzola et al, 2013;Cesano and Scarano, 2018;Chowdhury et al, 2019;Harun et al, 2019).…”

Electrical conductors based on carbons have recently attracted a growing interest due to the prospect of replacing metals. Electrical conductors without metals could represent not only an alternative for traditional wiring, but also a step forward in the progress and advancing of technology. This result can be achieved by combining high electrical conductivity with other properties, that are dexterity, light weight, environmental stability, high strength and flexibility. As the best mechanical properties, high electrical/thermal conductivity of the assembled fibers are all generally associated with low concentration of defects in the fiber backbone and in the individual carbon "building blocks", a special attention is paid to an empirical relationship between morphology/structure/composition and the electrical properties. In this review, starting from the beginning, from the late 19th century, when the carbon filaments became the lights for urban streets, some of the recent developments in the field of "all-carbon" electrical conductors are discussed. Such conductors can be obtained by assembling nanoscale carbons (i.e., carbon nanotubes, graphene) into macroscopic fibers, yarns and ropes (hereafter fibers). In this perspective, the role played by the chemistry in particular by means of the molecularlevel control and doping, is emphasized. This contribution elucidates most recent results in the field, and envisages new potential applications.
