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

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.
