讲座题目:From material modeling to Li-ion Battery life prediction
——- a closer look at the degradation mechanisms
ABSTRACT:
Many failure mechanisms in lithium ion batteries can be attributed to the continuous growth of a thin passivating film on electrode surfaces known as the solid electrolyte interphase (SEI) and the microstructural evolution during cycling. Constructing a predictive life model from a bottom-up approach requires a full understanding of each failure mechanism and many accurate material properties input. In this presentation, predictive modeling starting from first principles calculations was developed to compute important mechanical and diffusion properties of electrodes, idealized SEI components, and porous separators.
