ELECTRODE RESISTANCE MEASUREMENT SYSTEM RM2610

Quantify composite layer resistance and interface resistance in Li-ion battery electrode sheets

MORE INFO
SKU: RM2610 Categories: ,

Description

The RM2610 isolates and quantifies the resistance characteristics of electrode sheets, a major component of lithium-ion batteries (LIBs), as two components: the composite layer resistance and the interface resistance between the composite layer and collector.  The system allows users to visualize these two quantities by measuring the surface of the electrode sheet with a test fixture that consists of an array of test probes and then using proprietary analytical techniques to quantify them.

Key Features
• Measure composite resistivity [Ωcm]
• Measure interface resistance between the composite layer and current collector [Ωcm^2]

Electrode Resistance Measurement System RM2610 - From Setup to Testing

The HIOKI RM2610 separates the resistance of the positive and negative electrodes of lithium-ion batteries (LIB) into composite layer resistance and interface resistance (the contact resistance between the current collector and the composite layer) and quantifies the results for further analysis. This video shows how to set up and begin measurement.

Electrode Resistance Measurement System RM2610 - How to Perform Regular Maintenance

Introducing the procedures to verify continuity between the probes, resistance meter and DUT, as well as the insulation between probes. Because the test fixture does not have to be removed from the system but simply rotated to orient the probe head forward, cleaning and inspecting the probe is extremely easy.

Basic specifications    *The RM2611 Electrode Resistance Meter requires regular calibration. For more information about calibration, please contact your HIOKI distributor
