HIOKI RM2610 Electrode Resistance Measurement System

Quantitative Electrode Sheet Evaluation

The RM2610 evaluates two key electrical properties of lithium-ion battery electrode sheets in a single measurement cycle: composite layer volume resistivity and interface resistance between the composite layer and the current collector.

By separating resistance components that are difficult to isolate using conventional resistance measurements, the system provides quantitative data for material development, production process optimization, and quality assurance before cell assembly.

Key Features

Two Resistance Parameters

Simultaneously calculate composite layer volume resistivity and interface resistance between the composite layer and the collector foil.

Results Within a Minute

Obtain quantitative electrode resistance results within one minute to support efficient evaluation during development and production.

Multi-point Probe Measurement

A probe head equipped with 46 ultra-fine probes measures the electrode surface from multiple points for reliable resistance analysis.

Contact Check

A contact check function verifies electrical contact for each probe and supports reliable measurement with configurable threshold settings.

Two Key Parameters for Electrode Evaluation

The RM2610 separates the electrical characteristics of the electrode sheet into two quantitative resistance parameters.

Composite Layer Volume Resistivity

Quantifies the electrical resistivity of the composite layer of the electrode sheet and provides data for evaluating electrode material composition and conductive characteristics.

Interface Resistance

Quantifies the resistance at the interface between the composite layer and the aluminum or copper current collector foil.

Measurement and Analysis Principle

The RM2610 combines multi-point resistance measurement with numerical analysis to separate composite layer volume resistivity and interface resistance.

Contact

The 46 ultra-fine probes contact the surface of the electrode sheet.

Measure

Current is applied between selected probes and the resulting potential distribution is measured from multiple directions.

Calculate

RM2612 Resistance Calculation Software uses numerical analysis to calculate the unknown resistance parameters.

Evaluate

Composite layer volume resistivity and interface resistance are output as quantitative electrode evaluation results.
