摘要：The integration of phase change materials (PCMs) represents a promising approach for mitigating thermal runaway (TR) propagation in electrochemical energy storage systems, as their phase transition enables significant heat absorption. However, composite PCMs exhibit a wide range of thermophysical properties, and the mechanisms through which they suppress TR under different critical conditions remain insufficiently clarified. In this study, the inhibition behavior of composite PCMs is systematically examined under critical property distributions, both as standalone materials and in combination with insulator strategies. Various factors are examined to assess the effectiveness of the proposed strategies, including the variation effect of state of charge (SOC) and cell spacing. The results indicate that increasing SOC from 30% to 70% markedly alters thermal stability and propagation behavior, while enlarging cell spacing from 1 mm to 2 mm delays peak temperature occurrence, reduces the temperature rise rate, and slightly lowers peak temperatures, thereby slowing the overall thermal response, although propagation still occurs. When composite PCMs are coupled with insulating layers, the integrated system demonstrates substantial suppression performance. Compared with CPCM-only configurations, the CPCM/insulator designs reduce the temperature rise rate by approximately 75-85%, depending on the specific CPCM/insulation pairing. These findings provide valuable theoretical insights and recommendations for the safety design and risk assessment of battery packs.
