“…It was reported that MoS 2 /PANI hybrid could achieve a capacitance retention of 88% after 1000 cycles at 50 mV s −1 . The manganese hexacyanoferrate/PANI nanocomposite could achieve the specific capacitance of 730 F g −1 at 1 A g −1 and capacitance retention of 85% after 1000 cycles at 5 A g −1 . Alternatively, transition metal ion doping PANI composites are adopted to improve the stability of PANI .…”

Manganese (II) coordinated polyaniline (PANI‐Mn) is designed as an energy‐storage electrode to improve electrochemical cycling stability of conductive polymer‐based supercapacitors. A PANI‐Mn electrode is synthesized through electro‐polymerization and hydrothermal coordination processes. A tetrahedron coordination structure is formed between manganese (II) dichloride and neighboring imino nitrogen to enforce the bonding strength of conjoint aniline units, restraining excessive volume expansion of the PANI molecule chain. Specific capacitance is enhanced from 350 F g−1 of PANI to 810 F g−1 of PANI‐Mn at 1 A g−1. Cycling capacitance retention is improved from 61% of PANI to 88% of PANI‐Mn at 5 A g−1 for 1000 cycles. PANI‐Mn shows larger response current than PANI at the same potential. First principle calculations prove that PANIs‐Mn exhibits higher density of state at Fermi level than PANI. The conjugated electron delocalization is strengthened in transitional metal‐coordinated conductive polymer, causing the improved conductivity of PANI‐Mn. Furthermore, an all‐solid‐state symmetric supercapacitor based on a PANI‐Mn electrode exhibits an energy density of 51.38 Wh kg−1 at a power density of 850 W kg−1 and a considerable cycling life of 82% after 1000 cycles at 5 A g−1. PANI‐Mn coordination polymer exhibits enhanced electrochemical stability, thus showing promise for energy storage application.

“…However, the CuO@PANiNFs nanocomposite exhibits only 12% deterioration of specific capacitance after 1000 cycles and still retains less than 80% of its original capacitance after 2000 cycles, which is better performance in capacitance retention than previously reported PANi-based electrodes. 28,[45][46][47][48][49][50] The energy density (E) and power density (P) of CuO@PANiNFs nanocomposite were calculated from the Equations ( 3) and (4), respectively.…”

Copper oxide-decorated polyaniline nanofibers (CuO@PANiNFs) nanocomposite was prepared through in situ chemical deposition of CuO nanoparticles on the PANiNFs.The results of spectroscopic analyses suggested the presence of strong interfacial interactions between CuO nanoparticles and PANiNF matrix, while X-ray diffraction (XRD) analysis confirmed the formation of CuO monoclinic crystal phase on PAN-iNFs. SEM images displayed a uniform dispersion of CuO nanoparticles on the surface of PANiNFs. The highest specific capacitance of 486.9 F/g and area specific capacitance of 169 F/cm 2 at 0.5 mA/cm 2 were achieved for the CuO@PANiNFs nanocomposite. This could be ascribed to the low solution resistance and chargetransfer resistance of nanocomposite electrode as observed in the electrical impedance spectroscopic results. The CuO@PANiNFs electrode revealed good cyclic stability with $82% capacitance retention after 2000 cycles. The CuO@PANiNFs electrode delivered a maximum energy density of 67.7 Wh/kg, which is nearly 1.8 times higher than that of the pure PANiNFs electrode. Therefore, the present CuO@PANiNFs nanocomposite with high specific capacitance and energy density could be used as a cost-effective, ecofriendly, and sustainable supercapacitor electrode material.
