Lithium battery industrial park can make full use of the advantages of resources to achieve scale production of lithium battery,but the energy consumption intensity is large, and brings energy and link problems, so it is necessary to optimize the production processand achieve low-carbon development. At present, there are many researches on the process optimization of lithium battery manufacturingprocess, but there are less researches on the analysis and optimization of system performance at the campus level. The purpose is to studythe characteristics of energy production and consumption in lithium battery industrial park, and put forward the optimization and improve?ment scheme of the system. Firstly, the steady-state model of typical equipment and links in the lithium battery industrial park is estab?lished. Then, the exergic analysis and thermal economic analysis model of exergic analysis and thermal economic analysis of industrialpark based on Sobol method are built. Finally, the feasibility and effectiveness of the proposed method are verified by an example analysis.The calculation results show that hot blast furnace has the lowest exergic efficiency and the highest total exergic cost in the park, and hasthe highest impact on the exergic cost of system products, so it is necessary to focus on improving its performance.
