Abstract
Description
technical field
[0001] The invention relates to poly(3,4-ethylenedioxythiophene), its synthesis method and its application in supercapacitor electrode materials. Background technique
[0002] With the rapid growth of population and the rapid development of social economy, the gradual shortage of resources and energy, and the deteriorating ecological environment, human beings will rely more on clean and renewable new energy. In recent years, the demand for higher power density in many energy storage device applications has exceeded the standard design capabilities of current state-of-the-art batteries. Generally, in addition to requiring low cost and long life, it is more desirable to have a higher energy density per unit weight or unit volume (Wh / kg) or a maximum power density (W / kg). Electrochemical capacitors (EC), especially supercapacitors (ultracapacitors), have unique advantages in terms of power characteristics. Although their energy density is lower than that of re...
