ELECTRODE RESISTANCE MEASUREMENT SYSTEM RM2610

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

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. 

From Setup to Testing - Electrode Resistance Measurement System RM2610

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.

Key Features

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

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.

Accelerate the Evolution of LIB R&D and Quality Control at the Electrode Sheet Stage

Open new horizons in your research of the electrode sheet by gathering data that was never before available.
Hioki’s new system is able to separately acquire the resistance of the composite layer and the interface resistance between the composite and the current collector.
This is done by measuring the potential at the electrode sheet surface and using a proprietary Hioki analytical technique to isolate each of these resistances.
