Modeling the Microstructural and Micromechanical Influence on Effective Properties of Granular Electrode Structures with regard to Solid Oxide Fuel Cells and Lithium Ion Batteries

Ott, Julia Katharina

Abstract:
The work studies electrode structures and the influence on the performance of electrochemical cells. Porous electrodes structures are modeled as a mixture of electron and ion conducting particles, densified considering manufacturing: sintering of SOFC is approximated geometrically; calendering and intercalation in LIB are modeled by a discrete element approach. A tracking algorithm plus a resistor network approach allow predicting connectivity, conductivity and active area of various structures.
