What's in in your batteries?

  • Battery performance, efficiency and lifespan need a dramatical improvement.

  • Quality assessing of batteries is critical

  • Digesting battery samples is typically challenging

Superior sample prep: Elemental analysis of Li-Ion battery materials

The quality and performance of Li-ion batteries requires elemental analysis of battery components in several steps of the value chain. For example, starting with raw materials, quantitation of the primary elements helps to determine the most appropriate extraction approach. In battery production, it is used to control impurities, as they directly impact the performance and lifespan of the batteries. Elemental analysis is also used during recycling to help purify valuable materials. Sample preparation is the first fundamental step in ensuring reliable analysis and providing appropriate solutions for both ICP-OES and ICP-MS. Due to the variety of samples and their respective natures, from organic (like graphite) to inorganic (like ores), the sample prep protocol must ensure complete digestion to achieve the high-quality analyses required in this market.

Microwave-assisted sample preparation of α-spodumene: A simple procedure for analysis of a complex sample

Raw materials in the Li-ion industry are often complex matrices, which requires aggressive sample preparation conditions. The following study is focused on the development of a reliable protocol for the chemical analysis of a raw material, the α-spodumene, using microwave sample preparation. The aluminosilicate structure of α-spodumene has to be destroyed through the sample preparation in order to bring all the target elements in solutions and perform their analysis.
Taking into account the technological relevance of Li-ion batteries for electric vehicles, the authors describe how a simple and practical procedure without using concentrated HF was developed for chemical analysis of α-spodumene.
