“…Similar to LIBs, as a conductive polymer, PANI itself is also an ideal cathode material for SIBs. Nanostructured PANI like nanofiber PANI presented considerable specific surface area and electrical conductivity, moreover, PANI with high flexibility effectively improved structural stability and cycling stability [150,151].…”

Conducting polyaniline (PANI) with high conductivity, ease of synthesis, high flexibility, low cost, environmental friendliness and unique redox properties has been extensively applied in electrochemical energy storage and conversion technologies including supercapacitors, rechargeable batteries and fuel cells. Pure PANI exhibits inferior stability as supercapacitive electrode, and can not meet the ever-increasing demand for more stable molecular structure, higher power/energy density and more N-active sites. The combination of PANI and other active materials like carbon materials, metal compounds and other conducting polymers (CPs) can make up for these disadvantages as supercapacitive electrode. As for rechargeable batteries and fuel cells, recent research related to PANI mainly focus on PANI modified composite electrodes and supported composite electrocatalysts respectively. In various PANI based composite structures, PANI usually acts as a conductive layer and network, and the resultant PANI based composites with various unique structures have demonstrated superior electrochemical performance in supercapacitors, rechargeable batteries and fuel cells due to the synergistic effect. Additionally, PANI derived N-doped carbon materials also have been widely used as metal-free electrocatalysts for fuel cells, which is also involved in this review. In the end, we give a brief outline of future advances and research directions on PANI.

“…Conductive polymer polyaniline (PANI) is considered as a dependable pseudocapacitance material due to its fascinating properties such as its high specific capacitance, conductivity, environmental stability, and low cost. 10,11 Usually, PANI can be synthesized by electrochemical synthesis, spin-coating methods, and chemical oxidation and be widely applied. [12][13][14] Yang et al 15 fabricated PANI materials with nanocapsule structure, and the results showed high specific capacitance (502 F g −1 ) and outstanding cycle stability.…”

Summary In this work, the binary N‐CDs@PANI hybrids were fabricated by introducing zero‐dimensional nitrogen‐doped carbon dots (N‐CDs) into reticulated PANI. Firstly, N‐CDs were prepared by one‐pot microwave method, and then, the N‐CDs were introduced into in situ oxidative polymerization of aniline (ANI) monomer. The N‐CDs with abundant functional groups and high electronic cloud density played a significant role in guiding the polyaniline‐ordered growth into intriguing morphologies. Moreover, morphology‐dependent electrochemical performances of N‐CDs@PANI hybrids were investigated and N‐CDs improve static interaction and enhance the special capacitances in the N‐CDs@PANI hybrids. Especially, the specific capacitance of PC4 hybrid can reach 785 F g−1, which exceed that of pure PANI (274 F g−1) at current density of 0.5 A g−1 according to three‐electrode measurement. And the capacitance retention of the PC4 hybrid still keeps 70% after 2000 cycles of charge and discharge. The N‐CDs@PANI hybrids can have potential applications in electrode materials, supercapacitors, nonlinear optics, and microwave absorption.

“…PPY hollow spheres exhibited a specific capacity of 100 mA h g À1 , stable cyclability, and superior rate capability through reversible doping/de-doping reactions during the charge/discharge processes. Han et al [132] introduced polyaniline hollow nanofibers by using PMMA nanofibers as a sacrifice-template via an in-situ polymerization with a subsequent dissolution process. As cathode material for SIBs, the polyaniline hollow nanofibers exhibited a high reversible capacity of 153 mAh g À1 at 0.3 C (1 C = 150 mA g À1 ), high cycling stability (73.3% capacity retention after 1000 cycles), and decent rate capability (70 mAh g À1 at 8 C).…”
