In this work, we tackle the problem by merging a coupled model of mechanical stress and diffusion of Li-ions with a phase field description of an evolving crack. The novel approach allows us to study the evolution of the Li concentration together with the initiation and growth of a crack in an arbitrary geometry and without presuming a specific crack path.Technology: general issuesbicsscLi-DiffusionLi-Ion-BatteriesLithium-DiffusionLithium-Ionen-BatterienCrack GrowthPhasefieldPhasenfeldRisswachstumSpeicherpartikelStorage ParticlesTechnology: general issuesKlinsmann Markusauth1295563BOOK9910346775903321The Effects of Internal Stress and Lithium Transport on Fracture in Storage Materials in Lithium-Ion Batteries3023622UNINA
