The purpose of this study is to calculate the characterized, normalized, and weighted factors for the environmental impact of a Li-ion battery (NMC811) throughout its life cycle. To achieve this, open LCA software is employed, utilizing data from product environmental footprint category rules, the Ecoinvent database, and the BatPaC database for a comprehensive Cradle to Grave assessment.

The purpose of this study is to calculate the characterized, normalized, and weighted factors for the environmental impact of a Li-ion battery (NMC811) throughout its life cycle. To achieve this, open LCA software is employed, utilizing data from product environmental footprint category rules, the Ecoinvent database, and the BatPaC database for a comprehensive Cradle to Grave assessment. The findings of the current study that certain processes have significant environmental implications, including climate change (fossil), resource usage (energy carrier), resource use (minerals and metals), and respiratory inorganic impacts. However, it is noteworthy that water scarcity contributes to 87% of the overall effect, primarily due to the utilization of acids in the hydrometallurgical process. Moreover, the impact categories mentioned above are heavily influenced by the electricity grid mix employed during both the production and consumption phases. Consequently, increasing the proportion of clean energy in the electrical grid mix has been identified as an effective strategy for reducing the Life Cycle Impact Assessment (LCIA) of Li-ion batteries.••Life cycle assessmentLife cycle StagesLi-ion batteryNMC811Electric vehicles (EVs) account for the majority of current and forecast demand, but lithium-ion batteries are also used in consumer devices, essential defense sectors and stationary storage (electric grid). Around 24 % (emissions from energy) worldwide carbon dioxide (CO2) emissions come from transportation. To compete in the lithium-based bat. Life-Cycle assessmentThe International Organization for Standardization (ISO) is collection of standard describes LCA (ISO 2006b; a). According to Figure B1 in Appendix B, LCA contain 4 major phases: goal & scope definition, lifetime inventory analysis, life cycle impact assessment (LCIA) and interpretation. The characterisation stage transforms the emissions associated with the LCI inputs into the impact category indicator, like CO2-equivalent for climate change. It is achieved with the use of characterization factor, which designate various strength to emission with lower or higher impact inside a given impacts category. The normalisation and weighing procedures are not required by the ISO. These phases are marked by more uncertainty and subjective values. The normalisation provides impact to standard value by dividing the standard impact by the overall impact in the system, obtaining an impact value per overall. The weighting stage obtained by multiplying those normalised values by their weighting factors established to assess the relevance of different effectindicators. It is done to produce a single aggregated score for product's environment effect. It includes all Life Cycle Inventory (LCI) indicators needed by the preceding standards, as well as the European Commission's end-of-waste criteria and normalisation and weighting factor. This research compares the life cycle eval. The impact categories with more than 80 % weighted average value are considered. The cumulative single score displayed. The result is breakdown like the most significant effect impact factor categories which are responsible for cradle to grave analysis on open LCA. Also calculated characterized, normalized and weighting factor for EIF. Lastly the v.
