On the charge accumulation and ion exchange in PEDOT electrodes

Supercapacitors are devices that reside on the border between capacitor technology   and   battery   systems   and   are   utilized   in   transportation   and infrastructure applications. These are utilized to balance availability versus needs for high quality electrical energy.

The   cost   structure,   physical   properties   and   the eco-unfriendly characteristics of present supercapacitors hamper the development of future all-electric technology in our society. Thus, there is a need for a “green”, low-weight and low-cost supercapacitor technology.

Here, I suggest the development of high performing supercapacitors based on cellulose nanofibrils (CNF), conducting polymers, red-ox polymers and plasticized electrolytes, which can be manufactured using traditional paper manufacturing and printing technologies; the Power Papers technology. With this application I aim at identifying materials to improve the overall performance of paper-based supercapacitor targeting 400 F/g and an internal conductivity of 1000 S/cm and 20 S/cm for electronic and ionic charges, respectively. Further, the study also includes the development of a simple model toolbox to enable understanding and better design of Power Paper supercapacitors.
