“…6,7 Several review papers have been published in the past few years discussing nanostructured materials and conductive polymers and their applications in energy-related fields. 4,[8][9][10] In this review, we focus on the synthesis and characterization of different nanostructures of conductive polymers, and their promising applications and future opportunities in energy storage devices. For the synthesis and characterization, the conductive polymers are categorized by their structures: one-dimensional (1D) nanowires/nanorods/ nanotubes, two-dimensional (2D) nanostructured films, 3D nanostructured polymers and their nanostructured composites.…”

Conductive polymers combine the attractive properties associated with conventional polymers and unique electronic properties of metals or semiconductors. Recently, nanostructured conductive polymers have aroused considerable research interest owing to their unique properties over their bulk counterparts, such as large surface areas and shortened pathways for charge/mass transport, which make them promising candidates for broad applications in energy conversion and storage, sensors, actuators, and biomedical devices. Numerous synthetic strategies have been developed to obtain various conductive polymer nanostructures, and high-performance devices based on these nanostructured conductive polymers have been realized. This Tutorial review describes the synthesis and characteristics of different conductive polymer nanostructures; presents the representative applications of nanostructured conductive polymers as active electrode materials for electrochemical capacitors and lithium-ion batteries and new perspectives of functional materials for next-generation high-energy batteries, meanwhile discusses the general design rules, advantages, and limitations of nanostructured conductive polymers in the energy storage field; and provides new insights into future directions. Key learning points(1) General synthetic approaches and fundamental properties of 1D, 2D, and 3D nanostructured conductive polymers.

This work describes the performance of a gel polymer electrolyte (GPE) based redox capacitor using the cyclic voltammetry technique.GPE was prepared with 22.5 wt% polyacrylonitrile (PAN), (1:1weight ratio) ethylene carbonate (EC) and propylene carbonate (PC) having a salt concentration of 1.0 M sodium iodide (NaI). Dependence of ionic conductivity of GPE on temperature was investigated using ac impedance spectroscopy. Two polypyrrole (PPy) electrodes were used as the electrodes of the redox capacitor. The performance of the device was evaluated by cyclic voltammetry. The redox-capacitors were cycled at different scan rates to determine the scan rate at which the maximum capacitance is obtained. After tracking that scan rate, continuous cycling was carried out at that scan rate to investigate the deterioration of capacitance upon cycling. The room temperature conductivity (σ) of the GPE was 4.29 × 10 -3 S cm -1 . The conductivity variation with temperature followed the Arrhenius behavior. From the scan rates selected for the study, the maximum capacity could be obtained at the scan rate of 30 mV s -1 . The average specific capacity of the redox capacitor was 26.70 Fg -1 .

“…The supercapacitors derived from such PNCs are expected to provide a positive answer to the current demand for high-power energy storage systems with a reduced overpotential at high discharge rates [3]. Recently, a variety of PNCs based on graphene and its derivatives have been developed in combination with polyaniline [4,5] and polypyrrole (PPY) [4,[6][7][8] in an effort to explore the next generation of electrochemical supercapacitors for electrochemical energy storage. In this context, PNCs derived from PPY in combination with graphene and graphene oxide (GO) in various proportions have recently been studied for the development of electrochemical energy storage devices [6,[9][10][11].…”

An attempt was made to investigate the effect of the preparation temperature on the electrocapacitive performance of polypyrrole (PPY)/graphene oxide (GO) nanocomposites (PNCs). For this purpose, a series of PNCs were prepared at various temperatures by the cetyltrimethylammonium bromide-assisted dilute-solution polymerization of pyrrole in presence of GO (wt%) ranging from 1.0 to 4.0 with ferric chloride as an oxidant. The formation of the PNCs was ascertained through Fourier-transform infrared spectrometry, X-ray diffraction spectra, scanning electron microscopy and simultaneous thermogravimetric-differential scanning calorimetry. The electrocapacitive performance of the electrodes derived from sulphonated polysulphone-bound PNCs was evaluated through cyclic voltammetry with reference to Ag/ AgCl at a scan rate (V/s) ranging from 0.2 and 0.001 in potassium hydroxide (1.0 M). The incorporation of GO into the PPY matrix at a reduced temperature has a pronounced effect on the electrocapacitive performance of PNCs. Under identical scan rates (0.001 V/s), PNCs prepared at 10 ± 1°C render improved specific conductivity (526.33 F/g) and power density (731.19 W/Kg) values compared to those prepared at 30 ± 1°C (217.69 F/g, 279.43 W/Kg). PNCs prepared at 10 ± 1°C rendered a capacitive retention rate of ~96% during the first 500 cycles. This indicates the excellent cyclic stability of the PNCs prepared at reduced temperatures for supercapacitor applications.
