TY - JOUR PY - 2019// TI - Non-dimensional analysis of the criticality of Li-ion battery thermal runaway behavior JO - Journal of hazardous materials A1 - Huang, Peifeng A1 - Chen, Haodong A1 - Verma, Ankit A1 - Wang, Qingsong A1 - Mukherjee, Partha A1 - Sun, Jinhua SP - 268 EP - 278 VL - 369 IS - N2 - Lithium-ion batteries are the most popular used portable energy storage technology due to the relatively high energy density. While thermal instability induced safety concerns impede the pace of developing large scale applications, the practical applications have no tolerance for the catastrophic failure. To learn more about the characteristics of battery failure, the criticality of battery thermal runaway is studied in this paper. Semenov and Thomas models are employed to analyze the criticality of battery thermal runaway in uniform and nonuniform temperature distribution situations. In order to improve accuracy of prediction, the critical parameters of overall reaction are taken as a weighted average of four exothermic reactions and the critical criteria are revised by the consumption of reactants.

RESULTS from revised model are consistence with oven model. According to the revised thermal abuse models, the critical criterion (ψcrcr) and critical temperature distribution (θcr) are analyzed in different composite materials, convective heat transfer coefficients and cell deformations.

RESULTS give the variation of critical criteria and critical temperature with these factors.
