Scientists at Florida International University (FIU) have acquired a new X-ray diffractometer, enabling them to observe the internal processes of batteries as they operate. The Rigaku SmartLab X-Ray Diffractometer, now installed at FIU, is one of only two such devices in the United States—the other being at Rigaku’s U.S. headquarters in Texas.
The instrument analyzes materials by directing radiation beams and measuring how particles scatter, providing detailed information about atomic structure and composition. Its flexibility allows for quick reconfiguration to support various types of analysis.
Assistant professor Irina Chuvashova leads a team of 13 researchers from chemistry, physics, and engineering departments who are using the device to advance energy research and collaborate with industry partners. “Gaining hands-on experience with this technique equips our students with valuable skills that will significantly enhance their competitiveness in industrial careers after graduation,” Chuvashova said.
The team’s work includes studying battery behavior during charging and discharging cycles in real time—a capability not widely available among diffractometers. This research aims to contribute to developments in clean energy, advanced electronics, infrastructure resilience, and new materials innovation.
By examining batteries at an atomic level, researchers hope to create technologies that are more durable, charge faster, and have reduced environmental impact. The equipment may also help develop high-performance materials for use in sectors like aerospace and infrastructure.
