Core Viewpoint - The article discusses the release of the Lithium Battery Carbon Footprint Background Database V2.0, which aims to enhance the transparency and accuracy of carbon footprint assessments in the lithium battery industry, contributing to the sector's green and low-carbon development [1][3]. Group 1: Database Development - The V2.0 database was developed through collaboration among over a hundred organizations, including key enterprises and academic institutions, and will be officially launched at the 13th International Energy Storage Summit on April 10, 2025 [1][3]. - The database includes 830 data entries related to the lithium battery industry, covering the entire lifecycle of key materials such as cathodes, anodes, electrolytes, and separators, with 100% localization of carbon footprint factors [3][4]. - It encompasses 95% of material types in the lithium battery supply chain and accounts for 99% of the total carbon emissions throughout the lifecycle of lithium batteries [3][4]. Group 2: Data Quality and Methodology - The construction methodology of the V2.0 database is described as more scientific and transparent, with over 90% of the data quality evaluation reaching a superior level, and more than 90% of data collected post-2020 [3][4]. - The database is based on real enterprise data and employs Life Cycle Assessment (LCA) modeling, ensuring comprehensive data collection and calculation [3][4]. Group 3: Applications and Future Plans - The V2.0 database can be widely applied in carbon footprint accounting for materials/products in the lithium battery supply chain and in designing energy-saving and carbon reduction strategies [4]. - Companies can utilize the database to accurately assess product carbon emissions, develop targeted reduction measures, and enhance product low-carbon performance and market competitiveness [4]. - Future efforts will focus on continuously updating the lithium battery carbon footprint accounting system and database to support the green, low-carbon, and high-quality development of China's lithium battery industry [4].
