电动汽车的发展主要集中在锂离子电池上，这引起了科学、工业和政治对锂的兴趣。随着几项研究预测需求的强劲增长，关于该元素未来可用性的争议性声明正在流传。这表明有必要对全球锂循环进行更全面的了解。因此，进行了一项研究，以描述全球锂流动的物质流分析。基于2007年锂生产、制造和使用数据，建立了包含关键工艺流程的静态物质流模型。这项工作提供了第一个全球锂模型，并展示了锂的供应和需求以及流入环境的情况如何在全球范围内相互联系。虽然所使用的不同数据集有一些不准确之处，但可以确定生产和消费之间存在明显的差异，这需要进一步解释。所开发的静态全球锂模型既可以探索锂产品及其产生的物质流的回收可能性，也可以确定沿着生命周期的重要影响参数，这些参数可用于提高锂的资源效率。反过来，这对于提高锂等战略金属未来技术的资源安全至关重要。
Developments in electric mobility are strongly focussed on lithium-ion batteries entailing a rising interest in lithium by science, industry, and politics. As several studies forecast a strong increase of demand, controversial statements are circulating about the element's future availability. This indicates that a more comprehensive understanding of the global lithium cycle is necessary. Therefore, a study was carried out to describe the global lithium flows by means of a material flow analysis. A static material flow model of lithium comprehending key processes and flows was developed based on data about production, manufacture, and use for the year 2007. The work provides the first global lithium model and shows how supply and demand of lithium as well as flows into the environment are connected on a global scale. Whilst the different data sets used are subject to some inaccuracies, a noticeable discrepancy between production and consumption could be identified, which needs further explanation. The stationary global lithium model developed allows both to explore the recycling possibilities for lithium products and their resulting material flows and to identify important influencing parameters along the lifecycle, which can be used to increase the resource efficiency of lithium. This, in turn, is crucial to improving the resource security for future technologies of such a strategic metal as lithium.
