| Abstract Scope |
Elemental and chemical characterization are critical parts of progressing next-generation batteries from academic research to market production. Despite its importance, performing chemical characterization is traditionally difficult, time-consuming, and resource intensive.
This work presents a new mass spectrometry technique that addresses the limitations and challenges of traditional characterization methods. Combining Laser Ablation Laser Ionization (LALI) with Time-of-Flight Mass Spectrometry (TOF-MS), the new instrument can quantitatively measure lithium and other important elements spatially and in depth, under vacuum. Such capabilities support new battery chemistry development, optimum cell geometry design, and the characterization of failure mechanisms.
Measuring lithium distribution within battery electrodes is important for understanding charge and discharge cycles, characterizing the solid electrolyte interface layers, and identifying areas that may lead to lithium plating. Traditionally, reliably measuring lithium within air-sensitive electrodes is challenging. The presentation will explore the capabilities of LALI-TOF-MS for determining the distribution of lithium within battery electrodes. |
