Sammanfattning

All-solid-state batteries (ASSBs) are considered a next-generation technology with the potential to enhance the safety and extend driving range in electric vehicles. This study assesses the climate impact of two ASSB chemistries in 2025, 2030, 2040, and 2050, using a prospective life cycle assessment. The study accounts for changes in energy-intensive processes, secondary material use, and advances in battery design. A battery dimensioning model is developed to quantify material demand and the corresponding specific energies. The findings indicate that ASSB NMC811 with LLZO electrolyte likely has a higher climate impact than LIBs, while ASSB LFP with a polymer electrolyte has the potential to be achieve impacts comparable to LIB LFP. Minimizing non-cathode materials significantly lowers the climate impact of ASSBs, making them comparable to LIBs. Key contributors to the climate impact of both ASSBs are the electrolyte and cathode active materials, with the anode and current collector also important in polymer-based ASSBs. The analysis also shows the availability of lanthanum may pose constraint on scaling LLZO based ASSBs.
