日本語

EU電池規則とデジタル電池パスポート（DBP）の導入に伴い、リサイクルリチウムを含むリチウムイオン電池のカーボンフットプリント（CFP）算定の重要性が高まっている。本論文は、炭素活動ベースの粒度割当・統合メカニズムを提案し、EIS（ERP/MES/SCADA）のデータを活用して製品炭素データの取得と合理的な配分を支援する。リサイクル経路によりCFPは65%以上異なり、リチウム源の混合比率によって最大10倍の差が生じるため、正確な炭素活動の追跡が不可欠である。

English

With the EU Battery Regulation and Digital Battery Passport (DBP) implementation, accurate carbon footprint (CFP) accounting for lithium-ion batteries containing recycled lithium is critical. This paper proposes a carbon-activity-based granular allocation and integration mechanism using EIS data (ERP/MES/SCADA) to improve carbon data availability and allocation rationality. Results show CFP can differ by over 65% across recycling routes, and mixing primary and recycled lithium can cause up to tenfold differences, highlighting the need for precise carbon activity tracing.

日本のGX文脈において

日本では、蓄電池のCFP算定が国際競争力に直結し、SSBJ開示やサプライチェーン排出量算定の実務に応用可能。リサイクル材のCFP配分は日本企業の電池輸出やEU市場アクセスに影響するため、本提案は実務的な示唆を与える。

In the global GX context

This paper addresses the EU Battery Regulation and DBP requirements, offering a methodological approach for product-level carbon footprint allocation that is relevant to global supply chain disclosure and circular economy policies. It provides empirical evidence on the variability of recycled lithium CFP, informing international standards and corporate reporting practices.

📄 Abstract（原文）

With the gradual implementation of the EU Battery Regulation and the DBP (Digital battery passport), it has become critical to determine the carbon footprint of lithium-ion battery products that contain recycled lithium resources. However, the diversity of recycling pathways substantially increases the complexity of carbon footprint accounting and DBP construction for recycled lithium batteries. This paper proposes a carbon activity based granular allocation and integration mechanism. Built on organizational operational data in EIS (Enterprise information systems) (ERP (Enterprise resource planning)/MES (Manufacturing execution system)/SCADA (Supervisory control and data acquisition), etc.) and using carbon activities as the linkage for mapping, the mechanism supports the acquisition and sound allocation of product carbon data, thereby improving the availability of carbon data and the rationality of allocation throughout the accounting process, and enabling more robust product carbon footprint calculations. Across different recycling routes, the carbon footprint results for recycled lithium resources can differ by more than 65%. When considering spodumene as the lithium source, mixing primary and recycled lithium carbonate in varying proportions can lead to up to a tenfold difference in the carbon footprint of products containing recycled lithium. Therefore, precisely tracing the carbon emission activities associated with different lithium sources is crucial for enhancing the accuracy of carbon footprint accounting, promoting the sustainable development of lithium resources, and meeting the requirements of the new Battery Regulation and the DBP.
