Lithium is an increasingly important metal resource, especially within the context of expanding electrical energy storage requirements as the world seeks to transition to sustainable energy sources. As the primary ingredient in the most effective and broadly-applicable high energy-density battery technology (lithium ion and lithium air batteries), the increasing need for lithium as raw material has spawned increasing attention. We have previously developed robust analytical methods for the quantification of lithium in homogeneous brines, but these methods need to be optimized and expanded to allow for efficient quantification of lithium in heterogeneous brines. Furthermore, we seek to explore potentially new approaches to lithium separation for environmentally-sustainable extraction of lithium from brine deposits.

锂是一种越来越重要的金属资源，特别是在扩大电力供应的背景下。 随着世界寻求向可持续能源过渡，能源存储需求。作为首要 锂离子电池是最有效和最广泛应用的高能量密度电池技术（锂离子 和锂空气电池），对作为原材料的锂的日益增长的需求引起了越来越多的关注。我们 先前已经开发出用于定量均质盐水中锂的稳健分析方法， 但这些方法需要优化和扩展，以允许有效地量化锂中的锂。 非均质卤水此外，我们寻求探索潜在的锂分离新方法， 从卤水矿床中以环境可持续的方式提取锂。
