Abstract： In the context of global“dual carbon”，the lithium battery industry urgently needs to improve energy eficiency and undergo low-carbon transformation.International experience shows that the United States focuses on data-driven optimization，Japan focuses on process leanization，and Germany emphasizes overall energy efficiency improvement. In contrast， only 5% of China's production capacity reached the energy efficiency benchmark in 2020，whichis significantly lower than the target of 30% by2025.Thisarticle finds that electricity （60%～70% and natural gas （25%-35% ）are the main energy consumption in the production process，with coating drying （30%～45%） and chemical conversion process （40%） being the key energy consumption links.By implementing comprehensive measures such as coating waste heat recovery， chemical energy feedback，servo system optimization，and thermal system renovation， energy consumption can be reduced by 15%-25% .At the same time， establishing unified carbon accounting standards，promoting intellgent energy efciency management，and accelerating thereplacementof clean energy are key paths to promoting green development in the industry.This article provides a systematic technical solution for energyconservation and emision reduction in the lithium battery industry， which has important guiding significance for achieving the national"dual carbon” strategic goals.
