  • Page 96 What precautions apply when performing maintenance of probe tips? For more information about probe maintenance, refer to “RM9004 Test Fixture” (p.  1 18). Performing measurements while the tips of the probes are dirty will lead to probe wear and greater measurement error. Consequently, the probe tips should be cleaned regularly with air. Is it possible to verify that the system is making the same measurements every day? Yes.
  • Page 97 Why am I encountering frequent contact errors and measurement reliability errors? The instrument may not be properly acquiring the potential distribution. Possible causes include cases in which measurement current pathways are not well-formed in the test area, for example due to there being only a small amount of conductive auxiliary agent, or a mixture of locations where there is conductive auxiliary agent and other locations where there is none.

  • Page 98: About The Reduction Factor

    About the reduction factor 8.1 About the reduction factor In iterative calculations performed as part of an inverse problem analysis, calculations exhibit unstable convergence if the initial value differs greatly from the solution (making it more likely to encounter an error in which the interface resistance or composite layer volume resistivity is reported as a negative value).

  • Page 99: How Is Interface Resistance Calculated

    How is interface resistance calculated? 8.2 How is interface resistance calculated? By combining multipoint potential measurement (resistance measurement) and inverse analysis calculations, it is possible to isolate and calculate the composite layer volume resistivity and interface resistance for lithium-ion battery electrode sheets. In this way, it is possible to calculate interface resistance by means of a simple series of operations: configuring several settings, placing probes in contact with the surface of the electrode sheet, and stating measurement.

    What is volume resistivity? 8.5 What is volume resistivity? Volume resistivity is a physical property that indicates the comparative difficulty with which electricity passes through a material. It is also known as resistivity, specific resistance, and Ω electrical resistivity. Volume resistivity is measured in [ Each material has a characteristic volume resistivity that does not depend on its shape or size.

    What are analysis results? 8.8 What are analysis results? Analysis reliability provides an indicator of whether the inverse problem was performed correctly. Although the value is not intended to serve as an indicator of the absolute value or accuracy of the interface resistance or composite layer volume resistivity, it does offer a way to check the status of analysis.

  • Page 107: What Is Measurement Reliability

    What is measurement reliability? 8.9 What is measurement reliability? Measurement reliability provides an indicator of whether potential measurement has been performed correctly. It allows you to check the status of potential measurement. Measurement reliability is indicated by three values. Consistency [PASS/FAIL] Consistency provides a judgment of whether the magnitude of the gradient in the potential distribution accords with the theoretical result that would be expected.

  • Page 108: How Much Does Entering An Incorrect Value For The Composite Layer Thickness Affect Analysis Results

    Hioki evaluated the effect of entering an incorrect thickness when measuring a standard positive electrode sheet (with a composite thickness of 77 μm). This evaluation showed that the incorrectly entered thickness produced an error in analysis results on par with the ratio indicating the extent to which it differed from the correct thickness value.

  • Page 109: Under What Circumstances Do Contact Errors Occur

    Under what circumstances do contact errors occur? 8.11 Under what circumstances do contact errors occur? Contact errors are reported more often when the effect on measurement of the contact resistance between the probes and the measurement target becomes more pronounced. In terms of specific operation, 2-terminal resistance measurement is used to measure the resistance between the probes and the measurement target, and a contact error is concluded to have occurred if a certain threshold is exceeded.
