[Analysis Case] Evaluation of Lithium-ion Secondary Battery Electrode Materials

Evaluation of the dispersion of various components in the positive electrode composite.

It is possible to measure the resistance of electrode materials in lithium-ion batteries using SSRM (Scanning Spreading Resistance Microscopy). In electrode composites made up of components with different resistance values, it may be possible to confirm the mixing ratio of various materials as well as the presence of electrically active and inactive active materials. Additionally, by combining shape measurements such as AFM and elemental analysis, a comprehensive evaluation can be achieved.
