The test cell for individual battery testing utilizing the PAT-Core concept

The ECC-PAT-Core is the stand-alone test cell with PAT-Core. As a genuine member of the small volume ECC test cell series, the ECC-PAT-Core can be directly connected to a potentiostat. The ECC-PAT-Core test cell contains all necessary components for using the PAT-Core concept.

The ECC-PAT-Core is the ideal Li-ion test cell for small laboratories with up to 10 test cells running in parallel. It is the right choice to become familiar with the new PAT-Core concept before using the PAT series to the full extent.

In summary, the ECC-PAT-Core enables researchers to obtain outstanding results from two- and three-electrode battery tests on a small scale.

ECC-PAT-Core overview


Ability for conducting long-term half cell measurements with three electrodes over more than one thousand hours of battery operation

Fewer mistakes from corrosion and cross contamination

Increase of testing productivity by single-use concept

Measurement of half cell impedance spectra of unmatched quality

No need to clean or dry cell components

Fast assembly and dismantling lowers lead times of experiments

Easy and reliable electrolyte filling during assembly (defined electrolyte volume down to 0.05 cm³)

Reliable sealing with PE seal and double cutting rings

Reproducible and homogeneous mechanical pressure on electrodes

High precision 18 mm diameter sandwich geometry with a concentricity better than 0.1 mm (electrode and separator dimensions are compatible with other test cells of the ECC-series)

An upgrade kit is available for customers, who work already with ECC-Std, ECC-Ref or ECC-Combi test cells.
