Abstract

Microstructures of battery components largely affect electrochemical properties of the whole battery cell. In this context, especially physical phenomena occurring in their pores play a dominant role. However, experimental studies of these phenomena are hardly feasible. Therefore, the lattice Boltzmann method is applied to provide a detailed insight into the relevant processes at the pore scale. The following topics are covered: (1) electrolyte filling of structurally resolved lithium-ion battery electrodes, (2) impact of gas entrapment on battery performance, (3) development and validation of a new model for multi-phase flow in homogenized porous media, (4) chemical surface reactions, and (5) species transport in dynamically changing microstructures. The results give a first insight into how battery performance can be optimized by adapting structural and physico-chemical properties as well as process parameters.
