An ultrahigh-energy density and wide potential window aqueous electrolyte supercapacitor built by polypyrrole/aniline 2-sulfonic acid modified carbon felt electrode

Sibel Yazar et al.

Summary: In this study, excellent performance and wide operating voltage were achieved using an aqueous electrolyte in supercapacitors. Aqueous electrolytes are preferred over other electrolytes due to their safety, low cost, and non-toxicity. Polypyrrole (PPy) and aniline 2-sulfonic acid (ASA) modified electrodes were synthesized using a hydrothermal method on carbon felt (CFt) for supercapacitor applications. The concentration of ASA was found to affect the polymerization of PPy. Furthermore, an asymmetric supercapacitor (ASC) with a high operating voltage of 3.0 V was assembled using graphite plate and 3 M KCI. The CFt/PPy/ASA(0.02)//GP configuration exhibited a high specific capacitance of 902.9 F g(-1) at a scan rate of 5 mV s(-1) and retained 93.6% of capacitance after 5000 cycle-life testing at a scan rate of 1000 mV s(-1). The assembled ASC demonstrated an ultrahigh energy density of 1005 Wh kg(-1) and a power density of 3000 W kg(-1) at a current density of 2 A g(-1). The impact of ASA concentration on supercapacitor performance was observed.

Performance comparison of electro-polymerized polypyrrole and polyaniline as cathodes for iodine redox reaction in zinc-iodine batteries

Xiaofei Miao et al.

Summary: The electro-polymerization of polyaniline and polypyrrole on carbon felt was studied for zinc-iodine batteries, with the former showing better performance due to its porous structure compared to the dense structure of the latter. The porous PANI electrode proved to have higher capacity, stronger ability to suppress polyiodide ions shuttling, and better cyclic stability than the dense PPy electrode. Ultimately, the PANI@CF electrode demonstrated promising long-term performance and stability for actual application in Zn//I batteries.

Electrochemical synthesis and characterization of self-doped aniline 2-sulfonic acid-modified flexible electrode with high areal capacitance and rate capability for supercapacitors

Sibel Yazar et al.

Summary: In this study, a composite of polypyrrole and aniline 2-sulfonic acid (CFt/PPy/ASA(0.03)) was synthesized on carbon felt under acid conditions. The addition of ASA resulted in the growth of homogeneous and large grains on the surface, leading to improved performance of the supercapacitor. The flexible electrode exhibited high specific areal capacitance and excellent rate capability, and the device showed good retention of capacitance performance even after 2500 cycles in aqueous electrolyte. Therefore, the CFt/PPy/ASA(0.03) electrode plays an important role in practical applications of flexible, wearable, and portable electronics.

Relationships between polypyrrole synthesis conditions, its morphology and electronic structure with supercapacitor properties measured in electrolytes with different ions and pH values

A. . A. . Iurchenkova et al.

Summary: This study focuses on exploring the impact of different synthetic media on the atomic and electronic structure of polypyrrole, as well as its electrochemical properties in various electrolytes. It demonstrates that the properties of polypyrrole are closely related to the synthetic medium, nitrogen species, and oxygen-containing functional groups in the structure of the polymer. The specific capacitance of polypyrrole produced in acetonitrile is stable and reaches approximately 385 F g(-1) in 1M KCl aqueous solution over 10,000 cycles.
