Carbon materials are crucial due to their widespread application in industries like energy storage. Analyzing carbon helps ensure material quality and performance. However, its structural complexity and variability, such as the presence of defects and morphological disparities, pose challenges, making precise analysis difficult.

With the increasing demand for lithium-ion batteries, various compounds have been investigated as cathode materials. Typical examples include lithium cobaltite and lithium manganate, and the amount of oxygen deficiency is important as one of the items to evaluate the material properties. This is because deficient oxygen has an important influence on battery performance.

Proton exchange membrane fuel cells (PEMFCs) are getting more and more popular as a clean energy, and a lot of research is being done to achieve better durability for further spread into more commercial phase.

We obtained lithium-ion battery cells from 3 different commercial electric vehicles manufactured by an automotive company for the reverse engineering investigation. We disassembled and analyzed each of the cathode sheets, the anode sheets, and the separator sheets using multiple analytical instruments.

Proton exchange membrane fuel cells (PEMFCs) are getting more and more popular as a clean energy, and a lot of research is being done to achieve better durability for further spread into more commercial phase.

The HORIBA micro-XRF system performs two applications for proton exchange membrane fuel cell (PEMFC) catalyst research: One is Pt catalyst uniformity imaging within a catalyst sheet thanks to the imaging capability. The other is Pt catalyst loading mass determination on average, which is a popular application of EDXRF. Through the experiments, we successfully visualized aggregates of Pt catalyst in our samples, and we also got a good linearity of calibration curve for Pt catalyst loading mass determination.

We analyzed a Nickel Manganese Cobalt (NMC) cathode simulation sample using a HORIBA XGT-9000 X-ray analytical microscope and performed foreign matters analysis with the Particle Finding Module software.

We used the XGT-9000 to analyze foreign particles on a lithium ion battery material. We made a NMC cathode simulation sample and added Cu particles in the sample as simulated metal foreign matter.

We analyzed two slurry battery materials containing active material (NCM) and conductive agent (carbon). By using Partica CENTRIFUGE to analyze battery materials before and after kneading, results with distinctly different distributions were obtained, which enable us to infer the dispersion state of the battery materials.
