“…22,23 Currently, the most used materials for electrospinning are fossil-based organic polymers, such as polyacrylonitrile, polyimide, polyvinyl alcohol, polyvinylpyrrolidone, phenolic resin and asphalt. [24][25][26][27] Among them, electrospun PAN fibers have favorable spinnability and a high carbon yield (50%), and are the most used precursors for the preparation of CNFs because of their excellent flexibility and fiber formation ability during the electrospinning and carbonization process. [28][29][30] However, considering the economics and sustainability, natural polymers and their derivatives are regarded as the best alternative to replace synthetic polymers in producing carbon materials.…”

“…Carbon materials, such as graphene (G) [ 14 ], activated carbon (AC) [ 15 ], and carbon nanotubes (CNTs) [ 16 ], have excellent electrical conductivity but limited mass capacitance due to the electrochemical double layer capacitance (EDLC). Transition metal oxides (TMOs) such as MoO 3 [ 17 ], MnO x [ 18 ], V 2 O 5 [ 19 ], and RuO 2 [ 20 ] usually possess incredibly high theoretical specific capacitances. However, sluggish kinetics and poor electrical conductivity lead to severe capacitance fading and jeopardize the commercialization of FSCs.…”

Flexible supercapacitors (FSCs) are limited in flexible electronics applications due to their low energy density. Therefore, developing electrode materials with high energy density, high electrochemical activity, and remarkable flexibility is challenging. Herein, we designed nitrogen-doped porous MXene (N-MXene), using melamine-formaldehyde (MF) microspheres as a template and nitrogen source. We combined it with an electrospinning process to produce a highly flexible nitrogen-doped porous MXene nanofiber (N-MXene-F) as a self-supporting electrode material and assembled it into a symmetrical supercapacitor (SSC). On the one hand, the interconnected mesh structure allows the electrolyte to penetrate the porous network to fully infiltrate the material surface, shortening the ion transport channels; on the other hand, the uniform nitrogen doping enhances the pseudocapacitive performance. As a result, the as-assembled SSC exhibited excellent electrochemical performance and excellent long-term durability, achieving an energy density of 12.78 Wh kg−1 at a power density of 1080 W kg−1, with long-term cycling stability up to 5000 cycles. This work demonstrates the impact of structural design and atomic doping on the electrochemical performance of MXene and opens up an exciting possibility for the fabrication of highly FSCs.

“…Faradaic capacitors generally use a metal oxide/hydroxide as the cathode for efficient redox reaction on the electrode surface, which requires an electrode material with a large specific surface area and good electrochemical activity. Transition metal oxides and hydroxides [13,14], such as NiO [15], Ni(OH) 2 [16], Co 3 O 4 [17], MnO 2 [18], and RuO 2 [19], and their binary composites have been considered as optimized materials for SCs. The reversible redox reaction in faradaic capacitors occurs on the surface of the electrode, and because the electrical energy is stored on the electrode surface, the storage capacity of faradaic capacitors is significantly influenced by electrode material properties.…”

A binder-free porous NiCu(CO3)(OH)2 composite was grown on a polyacrylonitrile (PAN) nanofiber substrate using a hydrothermal method. PAN nanofibers were fabricated by the electrospinning method, thus producing a substrate with a nano-sized diameter and high specific surface area. The composite NiCu(CO3)(OH)2 nanowires on PAN nanofibers provided the large specific surface area required for the redox reaction. Transition metal-based nanowires and nano-sized PAN substrates indicate a synergistic effect in electrochemical performance. The NiCu(CO3)(OH)2 on PAN composite showed a remarkable maximum specific capacity of 870 mAh g−1 at a current density of 3 A g−1, which indicates that it can be a suitable electrode material. In addition, an asymmetric supercapacitor with NiCu(CO3)(OH)2 on PAN composite as the cathode and graphene as the anode showed an ultra-high energy density of 89.2 W h kg−1 at a power density of 835 W kg−1 and a capacitance retention of 90.1% after 5000 cycles.
