“…Electropolymerization of polyaniline can occur without the use of oxidants. Under a high electrical field, electrospinning produces nano or micro‐fibrous polymers, while electrospraying and electrospinning employ similar techniques, with only electrospinning yielding bulk polymer fiber structures [26] …”

The industrial and academic sectors have been closely observing the advantages of conventional polymers, primarily due to their easy preparation and low manufacturing costs. Recently, there has been a growing interest in conducting polymers (CPs) due to their unique characteristics. These polymers offer improved environmental durability, impressive mechanical and optical potential, ease of manufacturability, and a range of electrical properties compared to conventional inorganic materials. This review focuses on the chemical structures, properties, and synthesis of the most prevalent types of CPs. Furthermore, an analysis of conducting composites is conducted to evaluate their performance in energy storage devices. The review specifically focuses on the growth of their operations in energy storage technologies such as Lithium ion batteries, fuel cells, and supercapacitors (SCs). It also explores the current challenges faced by CPs potential applications for advancing energy storage systems. This review aims to advance understanding of the role of CPs for energy storage applications. In summary, conductive polymers offer a wide range of applications due to their unique features and suitable production techniques for energy storage system (ESS) application. However, there is still significant work to be carried out to enhance the performance of conduction polymers for ESSs. This overview has provided an introduction to traditional conductive polymers as functional materials, including information on their polymerization processes, advantages, disadvantages and the most promising ESS applications to date, such as various batteries and supercapacitors. It is worth noting that conductive polymers hold the potential to become crucial components in future ESSs. Achieving this potential will require further advancements in synthesis techniques, integration with other materials, as well as maximization and optimization of their capabilities.

“…Methods include emulsion polymerization, sol-gel polymerization, electrochemical polymerization, and matrix polymerization. Some methods, like oxidative polymerization, were used to prepare polyaniline (Varghese, KR, Kausar, & Pinheiro, 2023). The graphene-based PANI nanocomposites have been fabricated by various methods in the presence of graphene, rGO, or GO, and the PANI is in the form of nanoparticles: nanowires, Nanofibers, hollow spheres, or nanorods.…”

Including supercapacitors, rechargeable batteries, and fuel cells, conducting polyaniline (PANI) has been widely used in electrochemical energy storage and conversion technologies due to its high conductivity, ease of synthesis, high flexibility, low cost, and distinctive redox properties. Because of its poor stability as a super-capacitive electrode, pure PANI cannot keep up with the rising demands for more N-active sites, better power/energy densities, and more stable molecular structures. These drawbacks as a super-capacitive electrode can be overcome by combining PANI with other active materials such as carbon compounds, metal compounds, and other conducting polymers (CPs). Recent PANI research focuses mainly on PANI-modified composite electrodes and supported composite electrocatalysts for fuel cells and rechargeable batteries, respectively. Due to the synergistic effect, PANI-based composites with various unique structures have shown superior electrochemical performance in supercapacitors, rechargeable batteries, and fuel cells. PANI typically functions as a conductive layer and network in different PANI-based composite structures. This review also discusses N-doped carbon materials produced from PANI because they are frequently employed as metal-free electrocatalysts for fuel cells. We conclude by providing a quick summary of upcoming developments and future research directions in PANI

“…[2] Different from redox-active polymers that usually own low conductivity, conducting polymers such as polyaniline (PANI), polypyrrole (PPy), polythiophene (PTH) and their derivatives are also representative pseudocapacitive materials that are widely investigated as supercapacitor electrodes which has been detailed reviewed before. [9][10][11][12] Their higher conductivity as compared to most of the traditional polymers is mainly due to their conjugated structure of the backbone. Nevertheless, the conjugated chain structures conversely afford them high rigidity which is adverse for their application in electrode since the rigid polymer backbone is prone to suffering from mechanical damage upon high internal strain during charging and discharging process.…”

Due to their prominent power density, supercapacitors carve out a niche among all the energy storage systems. However, it is also well known that the energy density of supercapacitors takes no advantage over lithium‐ion batteries, the current star energy storage device. Therefore, substantial efforts have been paid to improving the energy density of supercapacitors not at the expense of its power density. To develop electrode with high capacitance is a direct and efficient way to increase the energy storage capability of supercapacitors. Organics whose molecular structure can be diversely designed to achieve high pseudocapacitance arising from redox active units in their backbone are good candidates as electrode materials for supercapacitors. Herein, this review summarizes recent progress of redox‐active organic electrode materials for supercapacitors and their pseudocapacitive energy storge mechanisms based on different organic functional groups. From the aspects of their preparation approaches, molecular design and the resultant electrochemical performances, the focus is to probe the relationship between the energy storage mechanisms and the molecular structure of redox‐active units and provide some insights for the further development of organic supercapacitor electrodes.
