Computational Analysis of the Mechanical and Thermal Stresses in a Thin Film PProDOT-Based Redox Capacitor
Published in 2008
Among the several types of capacitors, the double-layer and redox types have gathered increasing attention to address some of the heavy power demands of modern technology. In redox capacitors, charge is stored chemically via oxidation/reduction processes in the active materials like electroactive polymers (EAPs) or metal oxides. This work investigates the stresses and heat flux of the electrode – separator membrane interaction in a thin film redox capacitor at scales under a micrometer.
COMSOL Multiphysics was used to model the electrode. Results show significant stresses and deformations occurring in the PProDOT-based electrodes as well as temperature variations that provide a plausible explanation for the abrasion phenomena.
