Chemo-Mechanical Failure Analysis in Alloying Battery Electrodes

From the previous crystallographic design, I analytically construct the twin microstructure of Spinel LMO. However, the microstructural evolution pathways under dynamic discharge conditions for Spinel LMO remain unclear. To address this gap, I establish a continuum mechanics model that delves into the intricate relationship between diffusion and finite lattice deformation in phase transformation materials. This framework is adapted to intercalation materials, specifically Spinel LMO, enabling an investigation into the delicate interplay between Li-diffusion and the cubic-to-tetragonal deformation of lattices.
