Dimensionless normalized concentration based thermal-electric regression model for the thermal runaway of lithium-ion batteries

Advances and challenges in thermal runaway modeling of lithium-ion batteries

“…Cell-based reaction kinetic models refer to the temperature rise curve of the full cell measured under adiabatic conditions, such as that in ARC, which is utilized to estimate thermal kinetic parameters. 75 , 76 , 77 , 78 , 79 In this approach, the entire TR process is divided into several stages based on the temperature rise rate range, and each stage is linearly fitted individually to derive corresponding kinetic parameters for various ranges. 77 However, this model cannot elucidate the sequence of reactions or the kinetics of electrode materials during TR.…”

“…Recently, some modeling strategies have been proposed to identify thermodynamic parameters across the full SOC range, such as interpolating kinetic parameters 92 and developing thermal-electric coupled models based on dimensionless normalized concentration. 76 In addition, as next-generation batteries with novel chemical systems, such as all-solid-state and sodium-ion batteries, emerge, 93 , 94 , 95 , 96 , 97 there is a continued need to explore universal thermal kinetic models and matching parameters that can comprehensively encompass different chemical systems and cell states. Moreover, the current identification of kinetic parameters generally relies on extensive calorimetry testing to align with experimental results.…”
