Phase-field Modeling of Phase Changes and Mechanical Stresses in Electrode Particles of Secondary Batteries

Viac o knihe

The book explores a phase-field model for the cathode material NaxFePO4 used in Na-ion batteries, focusing on the phase changes and stress evolution that can damage electrode particles. It examines the effects of particle size and state of charge on the miscibility gap of nanoscale insertion materials. Additionally, the introduction of nonlocal species concentration theory highlights how nonlocality impacts the findings, offering insights into the behavior of storage materials under varying conditions.
