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.
