Study outlines pathways to cut lithium-ion battery emissions by 2050
Researchers from the University of Melbourne say that changes in battery production, longer lifespans and greater recycling could markedly lower carbon emissions from lithium-ion batteries by mid-century.
Tesla and Surun recently supplied 580 MW of power to the electricity network, highlighting the growing role of renewables. However, the researchers note that battery manufacturing consumes substantial energy, especially for lithium extraction, which tempers the climate advantage of electric vehicles. The University of Melbourne team projects that, by 2050, emissions from a single battery could be reduced through cleaner production, more efficient processes, low-carbon chemistries and higher recycling rates.
They also find that maintaining current battery lifespans could cut demand for new cells, while limiting capacity growth and repurposing retired batteries for local storage would further lower manufacturing needs. Combined, these measures could prevent several gigatonnes of CO₂ emissions by 2050. The study references complementary work from Sanford University on recycling benefits and cites Chinese firm Sunwoda’s new temperature-stable, ultra-fast-charging technology.
