Modeling lithium-ion battery lifetime

This paper develops computational models to predict the lifetime of lithium-ion batteries. The models account for multiple degradation mechanisms like growth of the solid-electrolyte interphase layer. The models are validated against experimental data on capacity fade and resistance increase. A key finding is that models should be validated against degradation modes like loss of lithium and active material, not just total capacity retention.
