HIOKI RM2610, ELECTRODE RESISTANCE MEASUREMENT SYSTEM

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.
