147953 - Electro-Chemo-Mechanics of Multiscale Active Materials for Next-Generation Energy Storage 

The battery electrode architecture, a long-standing design, combines active material particles, conductive carbon, and binder additives on a current collector. While microparticles have conventionally been used, nanoparticles are now gaining attention for their advantages in nanomaterial-based electrodes, including higher rates, power density, and toughness. However, their adoption is hindered by lower capacity, efficiency, and cost compared to microstructured counterparts. A promising solution is Multiscale Active Materials (MAM), integrating microscale materials with nanoscale pores. MAM, whether 'engineered' (E-MAM) or 'natural' (N-MAM), offers a blend of micro and nano benefits. This presentation will review progress in nanomaterial-based batteries, emphasizing the significance of MAM for future designs. It will also discuss preliminary findings on E-MAM and N-NAM, covering interface mechanics and intercalation mechanisms. The diverse stoichiometries involved in MAM structures present numerous possibilities, akin to finding a 'Needle in a Haystack.' The presentaion will describe how machine learning offers a revolutionary approach to identifying optimal energy storage materials for the next generation.
