“…It can be seen that each discharge curve has an apparent potential plateau corresponding to the reduction peak in CV (Ni 3+ →Ni 2+ ). Such good performance should be attributed to the intimate encapsulation of tiny activated Ni nanoparticles in the polyester fabric, which ensures both fast electron transport and rapid access to electrolyte (OH-) [32–34]. When the current density increase from 7.5 to 30 mA/cm 2 , areal specific capacitance of Ni plated polyester decrease from 450 mF/cm 2 to 350 mF/cm 2 (Figure 9).…”

In this research work, Nickel was in situ synthesized on polyester fabric using facile method. For this purpose, electroless plating method was used. In the first step, samples were sensitized using copper acetate. Hydrazine were used as reducing agent. In the same bath, Nickle acetate was added and in presence of hydrazine, the Nickle nano particles were deposited on the surface of polyester fibers. The morphological properties of nano particles on the surface were investigated using Scanning Electron Microscope (SEM). The electrical resistance of samples after metal plating were measured by two-point probe. The rubbing and wash fastness of samples through electrical resistance were also studied. The results show that, Ni plated sample has very high resistance to rubbing. Even after 8000 cycles of rubbing using Martindale system, the electrical resistance of rubbed samples reaches to 40 Ω/sq. But it should be mentioned that, the wash fastness of prepared samples is not satisfactory. The main purpose of this research was, investigating on the storage properties of Ni plated polyester fabric. The electrochemical properties of samples were investigated using cyclic voltammetry (CV) and galvanostatic charging–discharging (GCD) measurements (Autolab PGSTAT 302 N). The Ni plated polyester in this work, showed, a specific capacitance of 450 mF/cm2 by GCD test at the current density of 7.5 mA/cm2. Also the integrated area for the CV curves related to rubbed samples, is large enough. The resultant Ni plated fabric provides a promising substrate to prepare textile-based electrodes for flexile supercapacitors.

“…Generally, carbon fibers are brittle; therefore, it is very challenging to retain fibers in their free-standing and flexible state. There are some reports that show the successful fabrication of highly flexible carbon fibers, and they have been used to study electrochemical performance [130,131]. Tian et al showed interconnected networks of carbon fibers that improved the integrity and buffered the volume expansion of an electrode, while contributing to its flexibility [132].…”

The development of smart negative electrode materials with high capacitance for the uses in supercapacitors remains challenging. Although several types of electrode materials with high capacitance in energy storage have been reported, carbon-based materials are the most reliable electrodes due to their high conductivity, high power density, and excellent stability. The most common complaint about general carbon materials is that these electrode materials can hardly ever be used as free-standing electrodes. Free-standing carbon-based electrodes are in high demand and are a passionate topic of energy storage research. Electrospun nanofibers are a potential candidate to fill this gap. However, the as-spun carbon nanofibers (ECNFs) have low capacitance and low energy density on their own. To overcome the limitations of pure CNFs, increasing surface area, heteroatom doping and metal doping have been chosen. In this review, we introduce the negative electrode materials that have been developed so far. Moreover, this review focuses on the advances of electrospun nanofiber-based negative electrode materials and their limitations. We put forth a future perspective on how these limitations can be overcome to meet the demands of next-generation smart devices.

The development of smart negative electrode materials with high capacitance for use in supercapacitors remains challenging. Although there have been several types of electrode materials with high capacitance used in energy storage, carbon-based materials are the most reliable electrodes due to their high conductivity, high power density and excellent stability. The most common complaint about general carbon materials is that these as-formed electrode materials can hardly ever be used as free-standing electrodes. Free-standing carbon-based electrodes are in high demand and are a passionate topic of energy storage research. Electrospun nanofibers are a potential candidate to fill this gap. However, the as-spun carbon nanofibers (ECNFs) have low capacitance and energy density on their own. To this end, several attempts have been made to improve these characteristics. In this review, we introduce negative electrode materials that have been developed. Moreover, this review places special attention to the advances of electrospun nanofiber-based negative electrode materials and their limitations. Based on the above information, we put forth a future perspective on how these limitations can be overcome to meet the demands of next-generation smart devices.
