Technical Information Magazine 202003-01 Lithium-Ion Battery Materials
The technical information magazine The TRC News provides the latest information on analytical techniques that are useful for research and development, solving production troubles, and quality control.
**Abstract** In situ analysis techniques are essential for directly observing structural changes in electrode active materials during charge and discharge, as well as the distribution of reactions within batteries. By utilizing this technology, important insights can be gained that advance material development and cell design. Additionally, understanding the thermal stability and temperature dependence of the chemical structure of battery materials, not limited to when the battery is in operation, is effective for improving product performance. This paper introduces various in situ analyses we are conducting, including charge and discharge and temperature changes. **Table of Contents** 1. Introduction 2. In situ analysis using laboratory equipment 3. In situ Raman analysis of lithium-ion batteries 4. In situ XRD analysis of lithium-ion batteries 5. Examples of temperature-dependent physical property evaluations 6. Conclusion
