Visualization of Current Distribution by ZXY Measurement: Current Measurement of Graphite Sample

User Benefits

- Enables measurement of the current of sample surfaces with large and μm order irregularity. - Possible to acquire current images of composite material samples with solid and liquid components. - Application to electrode materials for secondary cells can be expected.

Introduction

Since conventional current measurements are conducted in the contact mode, measurement of samples with large surface irregularity and samples with high viscosity or a strong meniscus force was difficult due to the large external force in the reverse direction to the probe scanning direction. This report describes visualization of current distribution by ZXY measurement (Application News No.S47), which is relatively unaffected by these external forces. Application of this measurement technique to secondary cell electrodes with large surface irregularity due to carbon particles and additive materials is expected.
