This application note addresses the critical challenge of quantitatively measuring lithium distribution in battery electrodes which is essential for improving performance, capacity, and lifespan.
Analyzing pristine and cycled silicon anodes, the study reveals how different charging rates create distinct lithium accumulation patterns that may indicate plating or failure mechanisms.
Results demonstrate Massbox's capabilities for elemental mapping with adjustable spatial resolution, depth profiling to distinguish surface versus subsurface lithium distribution, and vacuum-based analysis with air-free transfer for handling sensitive battery materials.
The document showcases how three-dimensional lithium characterization accelerates research and development cycles for next-generation battery chemistries and optimized cell geometries.
