Multi Technique Characterization of Fuel Cell and Li-ion Battery Materials for QC and R&D

The U.S. has pledged to decarbonize its economy by 2050, and reducing emissions from the transportation sector is essential to achieving this goal. Lithium-ion batteries and hydrogen technologies offer promising solutions, but their widespread deployment is currently limited by high costs and material loadings. Material properties play a crucial role in the efficiency of these technologies, influencing complex transport processes and overall performance. Factors like material structure, element distribution in depth, and active component loading are critical for optimizing device efficiency.

 

To better understand and improve these materials, advanced analytical techniques are essential. Glow Discharge Optical Emission Spectroscopy (GD-OES) provides rapid, in-depth elemental distribution analysis up to 150 microns in just minutes. Complementary techniques like X-ray Fluorescence (XRF) and Raman spectroscopy offer chemical specificity and the ability to monitor structural changes non-destructively, quickly, and without contact. Raman spectroscopy is especially valuable for tracking changes in battery cells during charge and discharge cycles. This discussion will showcase applications of GD-OES, micro-XRF, and Raman spectroscopy for batteries and fuel cells, highlighting their role in advancing energy storage and conversion technologies.
