To deal with the flammability of PA (paraffin), this paper proposes a CPCM (composite phase change material) with a high heat-absorbing capacity for mitigating the thermal runaway of lithium-ion batteries. Two heating power levels were used to trigger thermal runaway in order to investigate the influence of heating power on thermal runaway characteristics and the mitigation effect of the PCM (phase change material). Thermal runaway processes and temperature changes were recorded. The results showed that heating results in a violent reaction of the battery, generating a high temperature and a bright flame, and the burning of PA increases the duration of a steady flame, indicating an increased threat. SA (sodium acetate trihydrate) effectively inhibited PA combustion, and the combustion time was reduced by 40.5%. PA/SA effectively retarded the rise in temperature of the battery, and the temperature rise rate was reduced by 87.3%. Increased heating power caused faster thermal runaway, and the thermal runaway mitigation effect of the CPCM was dramatically reduced. This study may provide a reference for the safe design and improvement of thermal management systems.

Phase change materials (PCMs) have garnered significant interest in the field of passive cooling for lithium‐ion batteries in recent years due to their simple structure, low cost, and stable performance. This paper introduces a passive thermal management strategy based on nonuniform paraffin (PA) and glass fiber for battery modules. It explores the impact of glass fiber on the thermal conductivity and structural strength of PA, as well as the thermal management performance of the composite phase change battery module that combines the two materials. The findings reveal that the composite phase change module with a glass fiber mass fraction of 60%, operating at a discharge rate of 3C, maintains a temperature 0.76°C lower than that of the air‐cooling module. This reduction results in a decreased maximum temperature difference between the modules from 7.3 to 5.0°C and a decrease in the maximum temperature ratio from 16.9% to 11.6%. Moreover, compared to the PA phase change module, heat transfer to adjacent cells decreases by approximately 10% during thermal runaway, effectively suppressing thermal propagation. Additionally, the incorporation of glass fiber in this scheme enhances the compressive strength of the module by a factor of 9.81. This study presents a novel method to address the thermal management needs of batteries for heat dissipation and thermal insulation.
