N2 - As the global market for lithium-ion batteries continues to grow, sourcing alternative materials for battery cell production gains interest and has an ever increasing potential to reduce environmental impact during the production phase. Around 97% of the produced Li-ion batteries contain a graphite-based anode, coated on a copper foil. In this Life Cycle Assessment the potential reduction of environmental impact over various categories during the production of batteries when using an anode production method by laser sintering Si-waste powder in an innovative process is investigated. The study provides an indication of environmental feasibility of the suggested production process, comparing the technical innovative process to currently available anode production processes. The impact comparison is made on the level of anode production (cradle to gate) with the potential to zoom out to the full battery production process in future work. Current results indicate that the overall impact of production increases 27% when using the suggested anode production process, with the results being sensitive to the amount of energy required for sintering and the allocation of impact towards the Si-waste. The impact of this switch of anode production method for the full Li-ion battery production will depend on the affected charge capacity and lifetime duration of an assembled battery module.
