Youtian’s paper appears in Acta Materialia

Youtian just published a paper “Stress-Induced Intercalation Instability” in Acta Materialia. In this work, we use linear stability analysis and phase-field simulations to prove a flat intercalation front of lithium or other solutes is made intrinsically unstable by misfit stress in battery compounds. As a result, lithium intercalation will tend to develop wavy fronts at typical battery (dis)charging rates already observed in experiments, a phenomenon that has impact on both rate performance and stress concentration. Nice job, Youtian!
