Abstract:

Rechargeable batteries are common in key national strategic development fields, such as electric vehicles, due to their high-energy density and high-cycle stability. During repeated charging and discharging, the uneven deposition of metal ions will lead to dendrite growth on the electrode surface, the reduction of reversible capacity and internal short circuit. Dendrite formation is an extremely complex process, which involves many disciplines such as electrochemistry, thermodynamics, kinetics and crystallography. And it is affected by multiple factors such as charging conditions, compressive stress, battery composition, temperature, magnetic field and so on. This paper systematically summarizes the theoretical models involved in dendrite nucleation and growth, comprehensively reviews the phase-field simulations in battery dendrites. The effects of charging condition, stress, external pressure and ion distribution on dendrite growth are discussed, and the research paradigm of electrochemical phase-field simulation in the field of battery dendrite is given. Subsequently, we apply an electrochemical phase-field model to investigate the influence of separator surface coating on ion distribution and dendrite growth uniformity. This work provides a theoretical basis for the design of dendrite inhibiting separator. Finally, the shortcomings of current phase-field simulations and future research directions are pointed out.
