Energy Reduction in Lithium-Ion Battery Manufacturing Using Heat Pumps and Heat Exchanger Networks

EasyChair Preprint no. 6984

Abstract

Global electric mobility is rapidly expanding. Hence, the demand for lithium-ion batteries is also increasing fast. Therefore, understanding energy minimization options in this rapidly growing industry is crucial for reducing the environmental impact as well as developing low-cost and sustainable batteries. The biggest contribution to greenhouse gas emissions is the cell manufacturing process. The most energy-intensive steps of cell manufacturing are electrode drying and dry room conditioning. Therefore, we developed process models for these two systems that can be used for evaluating various energy optimization techniques such as heat pumps and heat exchanger networks. Further, various process options can be tested and benchmarked in terms of their overall energy consumption using these models. The results show that the power requirement may be reduced through all the options assessed and available energy efficiency measures may substantially lower the energy footprint of cell production with strong relevance for subsequent greenhouse gas footprints.
