Electrode-resolved OCP, Full-cell pOCV, Pulse-resistance Measurements, Impedance Spectroscopy and Long-term Aging Data of Commercial Sodium-ion 18650 Cells (NMF Cathode / Hard-carbon Anode)

Cycling aging measurements of four commercial 18650 sodium-ion cells, electrode-resolved half-cell data from Na-RE T-cells, impedance spectra from TWRE T-cells, and degradation mode analysis results. The collection covers pOCV, RDC, GEIS/PEIS spectra, and related metadata.

This dataset contains experimental data measured in the scope of the experiments described in
