Micro Abstract:
Phase separation during the intercalation of lithium ions can lead to degradation effects in some cathode materials. A model describing lithium ion diffusion, electric potentials and small deformations is introduced on the microscale. The Cahn-Hilliard equation is used in an electrochemical model. coupled to linear elasticity of small strains in the electrode material. An immersed boundary method is used with adapative time steps. Charging of porous microstructures is numerically simulated.
