Research progress on PEDOT-based composites flexible high-performance supercapacitors

With the wave of technological advancement, energy storage for wearable devices is increasingly highlighted as a new challenge. To address this challenge in the field of energy storage, supercapacitors (SCs) prepared with the conductive polymer poly(3,4-ethylenedioxythiophene) (PEDOT) are emerging as the preferred solution for crossdomain energy storage. However, issues like inadequate energy density continue to plague PEDOT-based supercapacitors. This review aims to address these challenges by reviewing and critically analyzing the latest research results on enhancing the performance of PEDOT-based composite supercapacitors. First, we will provide an overview of the basic properties and characteristics of PEDOT-based materials, as well as the main methods used to prepare these materials. Subsequently, we will delve into how PEDOT-based binary and ternary composites can effectively enhance the performance of SCs. In addition, a brief overview of the applications of PEDOT-based materials in other fields will be presented to demonstrate their broad applicability. Finally, we will provide an outlook on the challenges faced by PEDOT-based and their composites in the field of supercapacitors and discuss their prospects.
