Future greenhouse gas emissions of automotive lithium-ion battery cell production

•We present a prospective life cycle assessment model for lithium-ion battery cell production for 8 battery chemistries and 3 production regions during 2020–2050.•GHG emissions per kWh of lithium-ion battery cell production could reduce by over 50% during 2020–2050, mainly due to expected low-carbon electricity transition.•Cathode component is, with 46%−70% for NCM/NCA cells and 33%−46% for LFP cells, the biggest contributor to GHG emissions of lithium-ion battery cell production until 2050.
