Critical review on life cycle carbon footprint assessment of lithium-ion battery
With the vigorous development of the electric vehicle industry,lithium-ion batteries(LIBs),as the core components of electric vehicles,have received extensive attention based on their environmental impact and sustainability.Under the background of dual-carbon policy,the carbon footprint evaluation of LIBs based on the full life cycle has become a key problem to solve the sustainable development of LIBs battery.Different studies have different research results due to differences in LIBs materials and recycling technologies.This paper summarizes the research progress of the full life cycle carbon footprint of LIBs,with the perspective"from the cradle to the grave"(full life cycle),"from the gate to the gate"(production stage),and"from the cradle to the cradle"(recovery stage),focusing on the production stage and the recovery stage.It is found that the carbon footprint of lithium iron phosphate batteries in the production stage is low.The benefit of hydrometallurgical recovery of lithium nickel cobalt manganese oxide battery is the best in the recovery stage.It is also found that the research and development of new technologies and the development and use of green energy can effectively reduce the carbon footprint of LIBs in the production,use and recycling stages of the full life cycle.Finally,this study looks forward to the future of multiple factors affecting the carbon footprint of LIBs and provides a basis for the sustainable development of LIBs and the realization of dual-carbon goals.
