Recent advances in MXene-based composite materials with conducting polymers for supercapacitors
Journal of Energy Storage(2024)
摘要
The fusion of conducting polymers with a two-dimensional (2D) structured MXene is regarded as an innovative solution in the realm of electrical energy storage, offering the potential to address the global energy supply challenge. These materials are an excellent candidate for supercapacitors (SCs). Various materials with conductivity can be utilized as effective electrodes in the context of SC applications. However, among these options, MXene stands out as a novel category of 2D materials with numerous advantageous attributes tailored for SC applications. However, the accumulation of MXene plates during synthesis reduces their capacity and performance. While techniques like sonication and the incorporation of metal ions as intercalating agents have gained popularity, employing conducting polymers such as polypyrrole (PPy), polyaniline (PANI), and poly(3,4-ethylenedioxythiophene) (PEDOT) emerges as a suitable resolution. The objective of this paper is to explore how different conducting polymers like PANI, PPy, and PEDOT influence the structure and characteristics of MXene. The study involves an examination of alterations in capacitance, electrical conductivity, and current density within supercapacitors utilizing MXene and these conducting polymers. This polymer significantly influences plate dispersion and MXene stability, offering a potential solution to enhance the efficiency of MXene in addressing the efficiency challenge. This article aims to investigate the effect of combining diverse conducting polymers on the SCs properties of the MXene and provide a vision for the future.
