[Analysis Case] Observation and Analysis of the Three-Dimensional Structure of Lithium-Ion Secondary Battery Cathode Materials

Capable of evaluating the distribution and structure of active materials in secondary batteries in three dimensions.

The structure of the active material used in the positive electrode of lithium-ion secondary batteries (hereinafter referred to as LIB) affects the battery performance. By using X-ray CT methods, three-dimensional observation images of the active material can be obtained, allowing for the observation of cross-sections at any location. Furthermore, by performing image analysis on the acquired three-dimensional images, it is possible to quantify various structural features. In this case study, the positive electrode material of the LIB was observed using X-ray CT, and an evaluation of the particle volume distribution of the active material was conducted. Measurement method: X-ray CT Product field: Secondary batteries Analysis purpose: Shape evaluation, structural evaluation, product investigation For more details, please download the materials or contact us.
