“…Future electronic devices, such assupercapacitors, organic solar cells, wearable electronic devices, and mobile phones, are expected to be thin, light, transparent and flexible [1][2][3][4][5][6][7][8][9]. Among them, the supercapacitor is attracting increasing attention because of its high power density and short charging time [10][11][12][13][14][15]. Especially, semi-transparent or transparent flexible supercapacitors demonstrate more attractive futures due to their great potential as integrated power sources for displays and windows, such as buildings and aerospace vehicles [16][17][18].…”

Herein, we report a flexible high-conductivity transparent electrode (denoted as S-PH1000), based on conducting polymer poly(3,4-ethylenedioxythiophene):poly(styrene sulfonate) (PEDOT:PSS), and itsapplication to flexible semi-transparentsupercapacitors. A high conductivity of 2673 S/cm was achieved for the S-PH1000 electrode on flexible plastic substrates via a H2SO4 treatment with an optimized concentration of 80 wt.%. This is among the top electrical conductivities of PEDOT:PSS films processed on flexible substrates. As for the electrochemical properties,a high specific capacitance of 161F/g was obtained from the S-PH1000 electrode at a current density of 1 A/g. Excitingly, a specific capacitance of 121 F/g was retained even when the current density increased to 100 A/g, which demonstrates the high-rate property of this electrode. Flexible semi-transparent supercapacitors based on these electrodes demonstrate high transparency, over 60%, at 550 nm. A high power density value, over 19,200 W/kg,and energy density, over 3.40 Wh/kg, was achieved. The semi-transparent flexible supercapacitor was successfully applied topower a light-emitting diode.

During the past decade, the electrically redox conducting polymers (CPs) have been delivering high capacitance and lower cyclic life due to their unique charge storage mechanism. Along with many advantages of CPs (their high conductivity, fast charge and discharge, and high specific capacitance), the main shortcoming of using them as the supercapacitor electrodes alone is that they are unstable over long cycle runs. Using CPs for long cycle runs during the redox reactions can not only lead to material loss but can also cause fractures or even breaking of the polymer chains during the reaction. Development of these flaws over a period can eventually breakdown the electrode.Polyaniline (PANI) is a special class of CPs that has been thoroughly examined as a good emerging supercapacitor electrode due to its large pseudo-capacitance and intrinsic redox states. [1] But as with CPs, during the process of charging/ discharging, PANI electrodes result in degradation leading to poor cycle life. [2] One solution of this inadequacy is to integrate PANI with any metal oxide material (TiO 2 , MnO 2 , NiO, Co 3 O 4 , and V 2 O 5 ) and/or carbon materials (activated carbon (AC), carbon nanotubes (CNTs), and graphene). It is seen that the electrochemical properties of PANI become more pronounced when PANI is combined with nanostructured TiO 2 (nTiO 2 ). [3] Carbon materials like AC have also established themselves as anode materials and have played crucial roles in the energy storage field because of their cost-effectiveness, high chemical stability, and good conductivity. [4] AC with high surface area has augmented electron transport efficiency that can transport ions, which are essential for preparing the carbon-based supercapacitors. On one hand, where carbon-based electrodes have excellent cycling stability but less energy density, CPs on the other hand have good conductivity but less stability. Also, nTiO 2 has already been verified as a promising candidate for

“…From 0.8 V to 1 V, PANI is subjected to a proper charge/discharge process; though, at less than 0.6 V, PANI is unworkable due to the minimum density of energy [ 208 ]. PANI is joined by the carbon group, such as carbon nanotubes and graphene, to be utilized in supercapacitors ( Figure 28 ) [ 78 ]. The polymerization for PANI graphene oxide produces homogenous PANI nanofibers that demonstrate extraordinary specificity, conductivity, and capacity but adequate cyclic stability [ 209 ].…”

Polyaniline (PANI) is a famous conductive polymer, and it has received tremendous consideration from researchers in the field of nanotechnology for the improvement of sensors, optoelectronic devices, and photonic devices. PANI is doped easily by different acids and dopants because of its easy synthesis and remarkable environmental stability. This review focuses on different preparation processes of PANI thin film by chemical and physical methods. Several features of PANI thin films, such as their magnetic, redox, and antioxidant, anti-corrosion, and electrical and sensing properties, are discussed in this review. PANI is a highly conductive polymer. Given its unique properties, easy synthesis, low cost, and high environmental stability in various applications such as electronics, drugs, and anti-corrosion materials, it has attracted extensive attention. The most important PANI applications are briefly reviewed at the end of this review.
