中国の電気自動車用バッテリー（NCMとLFP）をライフサイクル全体で比較評価。生産段階ではNCMの環境負荷が高く、リサイクルでは湿式冶金が優位。2060年には生産段階の排出が2023年比68.3%削減されると予測。
English
This study compares the life-cycle environmental impacts of NCM and LFP EV batteries in China. NCM has higher production-stage burdens; hydrometallurgy is the preferred recycling route. By 2060, production emissions are projected to drop by 68.3% from 2023 levels, supporting China's dual-carbon strategy.

📄 Abstract（原文）
Abstract In this study, a comparative life cycle assessment (LCA) of lithium nickel cobalt manganese oxide (NCM) and lithium iron phosphate (LFP) batteries from “cradle to grave” was conducted. The environmental impacts and carbon reduction potential of both NCM and LFP batteries in the production, using, and recycling stages were quantified and predicted through the ReCiPe 2016 Midpoint (H) method and Prophet model, respectively. Monte Carlo simulation and global sensitivity analysis were further integrated to quantify the uncertainty of life cycle environmental impacts, identify the dominant stages contributing to result variations, and evaluate the robustness of recycling route rankings across 18 environmental impact categories. It was found that NCM battery exhibited significantly higher environmental burdens than LFP battery in the production stage, primarily attributable to the energy-intensive mining and refining of nickel and cobalt. In the recycling stage, hydrometallurgy was identified as the preferred route for NCM battery, delivering a carbon offset of 71.34 kg CO2-eq and demonstrating a 98.6% probability of achieving a lower global warming potential (GWP) than pyrometallurgy. For LFP battery, hydrometallurgy also remained the preferred route, delivering a carbon offset of 7.30 kg CO2-eq and demonstrating a 100% probability of achieving a lower GWP than direct physical recycling. It was predicted that the carbon emissions in the production stage of NCM and LFP batteries in 2060 would decline to 49.6 kg CO2-eq and 36.1 kg CO2-eq, respectively, representing a reduction of 68.3% compared with 2023. The results obtained from this study were expected to provide scientific guidance for battery green design, recycling optimization, and policy formation by integrating deterministic environmental assessment with probabilistic robustness evaluation in support of the “dual carbon” strategy of China.
