Q.
What precautions apply when performing maintenance of probe tips?
A.
For more information about probe maintenance, refer to “RM9004 Test Fixture” (p. 118).
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.
Q. Is it possible to verify that the system is making the same measurements every
day?
A.
Yes. Use the probe check board to complete the pre-start inspection (p. 32) before you start
using the system daily. Inspection items include SHORT inspection (to check continuity among
the probes, RM2611 Electrode Resistance Meter, and the measurement target) and OPEN
inspection (to verify that probes are isolated from one other).
Q. How should I configure the settings for a collector with an undercoat?
Additionally, is it possible to evaluate an und collector sheet that lacks
a composite layer? (p. 101)
A.
Yes. You can evaluate such a sheet by ignoring the thickness of the undercoat when you enter
the conditions. The resistance value obtained by adding together the interface resistance
between the collector and the undercoat, the resistance of the undercoat itself, and the
interface resistance between the undercoat and the composite will be output as the interface
resistance.
Q.
It is possible to measure a sheet that has soaked up electrolyte? Additionally, is
it possible to measure an electrode sheet from a disassembled battery?
A.
If the electrode sheet is dry, yes. However, caution is necessary as any remaining electrolyte
will corrode and damage the probes.
Q. What are analysis results? (p. 102)
A.
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.
Q. What is measurement reliability? (p. 103)
A.
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, error rate, and variability (coefficient of
variability).
Q. How much does entering an incorrect value for the composite layer thickness
affect analysis results? (p. 104)
A.
How much entry of an inaccurate value affects analysis results depends on a variety of
parameters, including electrode sheet resistance, composite thickness, and collector thickness.
Please enter as accurate a thickness as possible before performing analysis. Additionally, the
system provides re-analysis capability to repeat analysis for previous measurements (p. 47).
