Charging Ahead: Raman-SEM Analyses of Li-Ion Batteries
Correlative Structural and Chemical Characterization of Energy Storage Materials
Understanding the relationships between battery cell composition, structure, and performance characteristics is crucial for the development of high-performance, long-life, and low-cost lithium-ion batteries. Chemical properties and structure of the anode, cathode, and separator can be visualized by combining Raman imaging, energy dispersive X-ray spectroscopy (EDS), and scanning electron microscopy (SEM). RISE microscopy integrates these three techniques into one instrument, making it a powerful method for battery research.
