DATASET EIS NYQUISTPLOT FEATURE EXTRACTOR¶
Extracts key electrochemical impedance spectroscopy (EIS) features from a Nyquist plot dataset, using the real and imaginary impedance columns as inputs. Use this worker to derive meaningful EIS metrics (e.g., bulk resistance, charge-transfer resistance, loop diameters) from raw impedance measurements for downstream battery or electrochemical analysis.

Inputs¶
| Label | ID | Type | Default | Required | Description |
|---|---|---|---|---|---|
| Dataset | dataset_1 | dataset | — | Input dataset containing the EIS Nyquist plot data, with at least one column for real impedance and one for imaginary impedance (tabular format, e.g., CSV-backed dataset); optional if data is passed via pipeline. | |
| Imaginary Data Column | im_column | text | — | Name of the column in the input dataset that contains the imaginary part of the impedance (e.g., ‘-Z_im’ or ‘Zimag’); leave empty only if the column name is auto-detected. | |
| Real Data Column | rl_column | text | — | Name of the column in the input dataset that contains the real part of the impedance (e.g., ‘Z_re’ or ‘Zreal’); leave empty only if the column name is auto-detected. |
Outputs¶
| Label | ID | Type | Description |
|---|---|---|---|
| dataset_drop_columns_output_1 | dataset_drop_columns_output_1 | dataset | Output dataset containing the extracted EIS Nyquist plot features (e.g., bulk resistance, charge-transfer resistance, semicircle parameters) derived from the real and imaginary impedance columns. |
