Production and applications of lead (II) oxide/poly(aniline-co-thiophene) composite materials for enhanced supercapacitor performance

Abstract

In this work, a novel approach was employed to prepare and utilize lead (II) oxide and poly(aniline-co-thiophene) (PANI-co-PTh) composite materials as electrode materials for supercapacitors, marking the first instance of such utilization in the literature. PANI-co-PTh was synthesized in bulk through chemical polymerization, and the conducting polymers underwent comprehensive spectroscopic, physical, and microscopic characterization. Subsequently, the material, incorporating lead (II) oxide (PbO) as a composite, was employed as electrode materials in asymmetric-type supercapacitors. The main results indicate a clear relationship between the surface area of conducting polymers and their specific capacitance. Notably, PANI-co-PTh-6, possessing the highest surface area, demonstrated the highest specific capacitance. Particle size distribution and specific surface area for PANI-co-PTh-6 were determined as 130 μm and 64.76 m2g−1, respectively. The PbO@PANI-co-PTh-3 configuration exhibited the highest specific capacitance, reaching 294 Fg−1 at a 10 mVs−1 scan rate. Remarkably, during long-cycle experiments, this system demonstrated a capacity retention of 70.69% after 1000 cycles. The inaugural application of the PbO@PANI-co-PTh-3 supercapacitor showcased notable capacitance values, establishing a substantial foundation for future research endeavors in this field.

“…They find applications in hybrid and electric vehicles, enabling uninterrupted use of renewable energy sources, as well as in portable devices such as laptops, cameras, power tools, and mobile phones, and in industrial equipment like elevators and cranes. 6,8,20 Different materials such as carbon nanotubes (CNTs), [21][22][23] reduced graphene oxide (RGO), [24][25][26] metal oxides/sulfides, 15,18,27 conductive polymers [28][29][30] have been used as electrode materials for supercapacitor applications. However, at this point, the high costs of metal oxides, low mechanical stability of conductive polymers, and high surface resistance of carbon-based systems pose significant problems.…”
