Mechanistic Insights into Nitrate-Pillared Co(OH)2/rGO Hybrids: Toward Supercapattery with Superior Rate Performance and Long-Term Stability

This dataset contains the experimental data supporting the findings reported in the manuscript entitled “Mechanistic Insights into Nitrate-Pillared Co(OH)₂/rGO Hybrids: Toward Supercapattery with Superior Rate Performance and Long-Term Stability", submitted to the Journal of Power Sources. The dataset includes the underlying numerical data for X-ray diffraction (XRD), X-ray absorption spectroscopy (XAS), cyclic voltammetry (CV), galvanostatic charge-discharge (GCD), electrochemical impedance spectroscopy (EIS), long-term cycling stability, and self-discharge measurements. These data support the structural, electronic, and electrochemical analyses presented in the manuscript and are provided to facilitate transparency, validation, and reuse of the reported results.
