Modeling Li transportation and degradation phenomena of Li-ion secondary batteries

In the design and operation of Li-ion secondary batteries, the characterization and technology of performance prediction by CAE is becoming increasingly important. Various simulation technologies have been developed, from a safety test including nail penetration, up to material characterization, such as the oxidation-reduction potential prediction of electrolyte and electrode. This paper introduces cycle characterization simulation technology that takes into account the degradation factor in charge and discharge processes, and the simulation technology of real electrode aggregation 3D structures; several analysis examples are provided.
