| 英文摘要 | The exponential growth in the consumption of lithium-ion batteries (LIBs) has resulted in a concomitant increase in the spent LIBs. Multi-component recycling is a highly desirable and beneficial process, yet the separator component remains overlooked. This study examined the thermal behavior, kinetics, thermodynamics, and evolved products of separator pyrolysis in N-2 and CO2 atmospheres. Furthermore, the conversion was modeled using Aspen Plus and a sensitivity analysis was conducted to investigate the impact of varying operating conditions. The findings indicated that the whole degradation process could be divided into three stages: below 200 degrees C, 200-550 degrees C and 550-900 degrees C. The evolved products at peak temperatures of 485 degrees C in N-2 and 500 degrees C in CO2 were composed of olefins and alkanes. The average apparent activation energy values were determined to be 222.78 kJ mol(-1) and 159.36 kJ mol(-1) in the N-2 and CO2 atmospheres, respectively. Thermodynamic analysis indicated that the separator decomposition was an endothermic and non-spontaneous process. Aspen Plus modeling results were in agreement with the experimental data. The sensitivity analysis revealed that an increase in temperature lead to an increased content of lighter compounds (<= C9) and a decrease in the proportion of heavier compounds (>C10) in the pyrolysis products. |
