요약 | This thesis investigates the electro-chemo-mechanics behavior of electrodes in lithium ion batteries. One of the critical challenges in advanced lithium ion batteries is preventing fracture and mechanical failure of electrodes during lithium ins |
요약 | Numerical simulations have the potentials for design optimization of lithium ion batteries. For traditional Newman's model, it is limited by the assumption that the electrodes are constructed with uniformly distributed spherical particles of equ |
요약 | Important parameters such as Young's modulus were investigated by ab initio tensile tests. The Young's modulus and ultimate strength of LixCoO2 under various lithium ion concentration were calculated. The observed Li concentration dependent mec |
요약 | The model was used to study the diffusion and mechanics behaviors in polycrystalline microstructures with varying grain size, grain boundaries and crystallographic orientations. It is found that the chemical diffusion coefficients increase with |
요약 | The developed model was also applied to study the diffusion induced stress in realistic microstructures reconstructed from FIB-SEM and CT. By simulating discharge processes, the results show that microstructure has a significant influence on the |
요약 | The model was extended to study the phase separation and stress generation. Th extended model can track the phase boundary implicitly and can be used in complex geometries. Compared with the elliptical and spherical particles, the stress in phas |
요약 | In summary, a multi-scale multi-physics microstructure based model was developed to evaluate the electro-chemo-mechanics in lithium ion batteries. The model can provide a computational tool for battery materials design. |
