This research focuses on testing the performance of sodium-ion batteries using variations in NaNO₃ electrolyte concentrations (1M and 4M) and solvent types (H₂O and DMSO), with the aim of determining the most effective combination. The objective of this study is to analyze the electrochemical characterization of TiO₂/NaNiPO₄ electrodes and to assess the influence of solvent and electrolyte concentration on battery performance. The NaNiPO₄ cathode was synthesized using the sol-gel method. Scanning Electron Microscopy (SEM) analysis revealed that both TiO₂ and NaNiPO₄ exhibited agglomerated particle morphologies with porous structures. X-ray Diffraction (XRD) analysis of TiO₂ showed eight diffraction peaks at 2θ values of 25.3°, 37.8°, 38.5°, 48.0°, 53.9°, 55.0°, 62.7°, and 75.0°, while NaNiPO₄ exhibited ten peaks at 10.38°, 20.14°, 20.70°, 31.76°, 34.78°, 45.46°, 49.48°, 56.49°, 66.21°, and 75.28°. The electrochemical performance of the TiO₂/NaNiPO₄ battery was evaluated using Cyclic Voltammetry (CV), Electrochemical Impedance Spectroscopy (EIS), Open Circuit Voltage (OCV), and Closed Circuit Voltage (CCV). The most stable CV results were obtained with the NaNO₃ 1M + DMSO electrolyte, showing the smallest ΔV value of 0.09766 V. The best EIS curve was also observed for the NaNO₃ 1M + DMSO variation, as indicated by the smallest semicircle diameter. In the OCV measurement, the highest initial voltage of 0.59 V was recorded for NaNO₃ 4M + DMSO. Meanwhile, CCV testing demonstrated that NaNO₃ 1M + DMSO achieved the highest power density of 0.15 W at a current close to 0.5 A. These results indicate that the NaNO₃ 1M + DMSO electrolyte provides the best performance due to enhanced ion mobility, stable electrochemical reactions, and lower internal resistance, thereby improving the overall efficiency of sodium-ion battery systems.
