[Analysis Case] Three-Dimensional Observation of Lithium-Ion Secondary Battery Electrodes
Observation of filling degree and voids using Slice and View.
The electrodes of lithium-ion secondary batteries are composed of active materials, conductive additives, and binders for both the positive and negative electrodes. The characteristics of the battery, such as capacity and reliability, are greatly influenced by the combination of materials, mixing ratios, filling density of active materials, and voids. Among these, FIB-SEM observation, which allows for processing and observation in a completely dry atmosphere, is very effective for observing filling density and voids. Furthermore, by conducting three-dimensional observation (Slice & View), it is possible to directly evaluate the condition of the electrodes.
