PEDOT, or poly(3,4-ethylenedioxythiophene), is among the most successful conducting polymer products because of its stable conductivity, colloidal processability, and rich assembly behavior. Since the very first patents on PEDOT filed in 1988, the material has been widely explored for decades in many applications. In this review, a comprehensive summary on the synthesis, processing and post-treatment of PEDOT will be presented for the sake of the discussion on PEDOT and its nanocomposites for energy storage. Knowing what PEDOT lends itself to the electrode materials is of importance to the rational design of energy storage devices that maximize the real-world performance. Based on these discussions, a roadmap for the development of PEDOT as promising multifunctional electrode component is presented.

PEDOT或聚（3,4-乙撑二氧噻吩），由于其稳定的电导率，胶体可加工性和丰富的组装性能而成为最成功的导电聚合物产品之一。自1988年在PEDOT上获得首项专利以来，这种材料在许多应用中已经进行了数十年的广泛探索。在这篇综述中，将对PEDOT的合成，加工和后处理进行全面总结，以期对PEDOT及其用于能量存储的纳米复合材料进行讨论。知道什么PEDOT适合于电极材料，对于合理设计能量存储设备以使实际性能最大化至关重要。基于这些讨论，提出了开发PEDOT作为有前途的多功能电极组件的路线图。
