Lithium-ion batteries (LIBs) have been proven as an enabling technology for consumer electronics, electro mobility, and stationary storage systems, and the steadily increasing demand for LIBs raises new challenges regarding their sustainability. The rising demand for comprehensive assessments of this technology's environmental impacts requires the identification of energy and materials consumed for its production, on lab to industrial scale. There are no studies available that provide a detailed picture of lab scale cell production, and only a few studies provide detailed analysis of the actual consumption, with large deviations. Thus, the present work provides an analysis of the energy flows for the production of an LIB cell. The analyzed energy requirements of individual production steps were determined by measurements conducted on a laboratory scale lithium-ion cell production and displayed in a transparent and traceable manner. For the comparison with literature values a distinction is made between the different production scales.
锂离子电池（LIBs）已被证明是消费电子产品、电动出行和固定存储系统的一项支撑技术，对锂离子电池不断增长的需求给其可持续性带来了新的挑战。对该技术环境影响进行全面评估的需求不断增加，这就需要确定从实验室规模到工业规模生产过程中所消耗的能源和材料。目前尚无研究能详细描述实验室规模的电池生产情况，仅有少数研究对实际消耗量进行了详细分析，但偏差较大。因此，本研究对锂离子电池生产过程中的能量流进行了分析。通过在实验室规模的锂离子电池生产中进行测量，确定了各个生产步骤的分析能量需求，并以透明且可追溯的方式呈现。为了与文献值进行比较，对不同的生产规模进行了区分。
